Labor and Production Barriers to the Reduction of Agricultural Chemical Inputs1

Abstract Advocates of sustainable agriculture consider farmer flexibility and innovativeness a key element in efforts to develop farm practices that reduce chemical inputs. In contrast to labor displacing technologies, farming with reduced chemical inputs may increase labor demands. Consequently, concerns about labor supply may affect farmer adaptability in reducing chemical inputs. This research addresses two specific questions. First, how concerned are farmers about the availability of labor needed to reduce chemical inputs? Second, do farmers view production problems as insurmountable without chemicals because of labor constraints? The majority of farmers surveyed agree that it is difficult to reduce chemical inputs because additional labor is hard to find, and their own labor inputs would have to increase. Results of OLS regression analysis show that whether the farmer hires workers affects the relationship between perceived labor and production barriers. Labor supply is less elastic for farmers who hire no labor, and they have less access to social networks that would provide them with sources of the additional workers needed if chemical inputs were reduced. The significance of these results for the development of sources of information that enhance farmer adaptability is discussed.     

THE SUPPLY OF INDIVIDUAL HOURS AND LABOR FORCE PARTICIPATION UNDER UNCERTAINTY

In the absence of labor supply constraints, this paper shows that an increase in wage-rate uncertainty alters the optimal supply of individual hours but leaves the decision to participate unchanged. In the presence of these constraints, it is shown that if researchers are concerned with obtaining consistent parameter estimates of the labor supply function, then it is important to correctly specify the type of uncertainty faced by workers. Specifically, a mean preserving increase- in wage-rate uncertainty lowers the participation rate, while an increase in non-wage income uncertainty raises participation.     

LIQUIDITY CONSTRAINTS WITH ENDOGENOUS INCOME

This article examines liquidity constraints within the household's intertemporal model with nonseparable consumption and leisure. The model includes wage income in the minimum wealth constraint. We derive an estimable equation for employed households that holds whether or not the family is credit constrained. The formulation enables direct testing for liquidity constraints. Empirical findings using the Panel Study of Income Dynamics strongly support the existence of debt constraints. Credit constrained households have significantly lower levels of consumption, disposable income, saving, and wage rates, a higher average propensity to consume, and smaller labor hours for the spouse but not the head.

Sexual Orientation,Unemployment and Participation: Are Gays Less Employable than Straights?

This paper is the first attempt to assess, in a unified econometric framework, the existence and the magnitude of both the sexual orientation participation gap and the sexual orientation unemployment gap. Having identified male same-sex couples using the Employment Survey, we use a bivariate probit selection model where the labor supply and the employment equation are jointly estimated for the French labor market. The results show that both participation and employment probabilities are significantly lower for gay employees compared to their heterosexual counterparts. Further investigations indicate that young gay workers, particularly, are more exposed to the unemployment risk than older ones. The beginning of a professional career and the subsequent entry to the labor market appear to be difficult steps to overcome for gay workers who spend more time than their heterosexual counterparts to find the good job.     

Erosion of purchasing power and labor supply

This paper presents three studies on the labor market in Italy, carried out using questionnaires over the course of time (1990–2002). The main result is that, if real wages decline to a certain extent, employed workers increase their labor supply, in order to recoup their lost purchasing power and to redress, perhaps unconsciously, the decline in their economic and social hierarchical position.As long as real wages grew at a satisfactory rate, in the early 90s, workers were unwilling to change their work schedules in either direction—exchanging income for leisure time at the current hourly wage or vice versa—whatever were their work time and wages. During the last decade workers—who suffered a decrease in real wages—have been willing to work more hours. As a result, workers did not demand more leisure time despite the fact that it had become cheaper as predicted by traditional theory. Thus, employers may expect a not-insignificant increase in labor supply if real wages decrease.     

The retirement system in transition: the 2007 Retirement Confidence Survey

WORKERS SLOW TO SEE OR ADAPT TO A CHANGING U.S. RETIREMENT SYSTEM: The 17th annual wave of the Retirement Confidence Survey (RCS) suggests that American workers may be slow to recognize how the U.S. retirement system is changing, and those who are aware of these changes may not be adapting to them in ways that are likely to secure them a comfortable retirement. HALF OF WORKERS LESS CONFIDENT ABOUT PENSION BENEFITS: The RCS finds pension-plan changes by employers have left nearly half of workers less confident about the benefits they will receive from a traditional pension plan, but that those experiencing a decline in retirement benefits often fail to react constructively. Moreover, although Americans will rely increasingly on 401(k) retirement savings plans and other personal savings and investments to fund their retirement security, data suggest that many may not follow professional investment advice when it is offered to them. MANY WORKERS COUNTING ON BENEFITS THAT WON'T BE THERE: Many workers are counting on employer-provided benefits in retirement that are increasingly unavailable. Only 41 percent of workers indicate they or their spouse currently have a defined benefit pension plan, yet 62 percent say they are expecting to receive income from such a plan in retirement. Likewise, workers are as likely to expect as retirees are to receive retiree health insurance through an employer, even though the number of employers offering this benefit to future retirees is declining. MANY WORKERS UNLIKELY TO HEED INVESTMENT ADVICE EVEN IF THEY GET IT: More than half of workers indicate they would be likely to take advantage of professional investment advice offered by companies that manage employer-sponsored retirement plans. However, two-thirds of these workers say they would probably implement only some of the recommendations they receive and 1 in 10 think they would implement none of them. AMERICANS OVERESTIMATE LONG-TERM CARE COVERAGE: One-quarter of workers and more than one-third of retirees report they have long-term care insurance (separate from health insurance, Medicare, and Medicaid) to help pay for care they might need in a nursing home, assisted living facility, or at home. But only 10 percent of Americans age 65 and older are estimated to have had private long-term care insurance in 2002, suggesting that many are counting on coverage they do not actually have. MOST SAVINGS LEVELS ARE MODEST: Almost half of workers saving for retirement report total savings and investments (not including the value of their primary residence or any defined benefit plans) of less than $25,000. The majority of workers who have not put money aside for retirement have little in savings at all: Seven in 10 of these workers say their assets total less than $10,000. CONTINUED IGNORANCE ABOUT SOCIAL SECURITY COVERAGE: Despite the longstanding increase in the eligibility age for Social Security, only a small minority of workers are aware of the age at which they can receive full retirement benefits from Social Security without a reduction for early retirement.     

Structural shifts in the employment of foreign workers in Austria

The full economic importance of immigration becomes clear only when one examines the concentration of immigrant workers in certain industries and occupations, and this is done in the case of Austria to show the degree of segmentation of the labor market between indigenous and foreign labor. In the course of the 1960s the employment of foreign labor gained importance in Austria. As a consequence, bilateral agreements with the major recruiting countries were made, e.g., with Spain in 1962 and 1969, with Turkey in 1964, and with Yugoslavia in 1966. The reason for the increasing demand for foreign labor was the short supply of indigenous labor due to increasing participation rates and strong economic growth. The demand-pull for foreign labor gained momentum with the onset of the economic boom in 1970, so that by the end of 1973 the number of foreign workers had doubled in comparison to 1970. The 226,800 foreign workers accounted for 8.7% of total employment. The 1974-75 recession and the weak economic development ever since resulted in a decreasing demand for labor. At the same time, the supply of indigenous labor increased as a consequence of a demographic effect and because of increasing participation rates of women. From 1981 to the present, foreign employment decreased again due to the unusually long period of economic stagnation. During 1983, 145,300 foreign workers were engaged, i.e., 5.3% of total employment. The structure for foreign employment now differs greatly from that in the 1960s. The share of women in foreign employment has increased steadily from some 20% in the early 1960s to 31% in 1973 and 40% in 1983 -- a value comparable to the Austrian female share in employment. The reduction of foreign employment since 1973 affected, above all, Yugoslav men. the share of Yugoslavs in foreign employment decreased from 196,300 or 79% in 1973 to 92,200 or 61.7% in 1983. With the duration of foreign employment rising, the disribution of foreign labor over economic branches increased. In the early 1960s the employment of foreign workers was concentrated in 3 branches -- the construction sector (32% of all foreign workers), metal industries (16%), and textile industries (10%). In 1982 only 1/3 of all foreign workers were still employed in these branches as an infiltration by foreign labor had taken place in all sectors. The services sector showed the greatest increase in foreign employment since 1975. There has never been as strong a concentration of 1 nationality in a particular economic branch as in Switzerland, Germany, or France. Case studies in Austria reveal that it was an explicit policy for firms (and also unions and entrepreneur representatives) not to depend on only 1 nationality of foreign workers. According to the case studies, about 1/3 of all foreign workers today occupy jobs which are in direct competition with indigenous labor. Another 1/3 fill jobs which are complementary to indigenous labor. For the remainder it is difficult to say to what extent they belong to one or the other segment of the labor market, because there is no information available on the occupational job structure.     

On the integration of labor markets: A definition and test of the radical — Segmentation hypothesis

The empirical results of this paper are indicative of overall labor market integration. Segmentation theories are not supported by the high covariability of wage rates supported by this test. If segmentation theories are to mean more than that relative wages differ among industries, proponents of such theories must argue that segmented markets are cut off from other markets and able to resist the forces of supply and demand. Indeed if labor unions are to be able to insulate workers from market forces they must also segment their markets. The results of this paper indicate that unions are not able to insulate their workers from market forces. We are grateful to William Boyes, Dennis Logue, John Bishop, Stephen E. Baldwin, William McEachern, Roger Sherman, and Robert Tollison for comments on earlier versions and to James Bennett and an unidentified referee for comments on this final version.     

Temporary Migration Overseas and Household Labor Supply: Evidence from Urban Philippines

The impact of international migration on the labor supply of workers' nonmigrant relatives has not been well documented in the literature. Using household survey data representing mostly overseas contract workers, i.e., temporary migrants, this paper shows that labor supplies of migrants and their nonmigrant relatives are inseparable. Migrants reduce the labor supply of nonmigrant relatives, which translates into lower earnings from local labor markets. Households substitute income for more leisure – a significant and previously little recognized benefit of emigration for Philippine households. This benefit varies by gender of nonmigrants and is generally higher for men.     

Temporary Skilled Migration to Australia: Employers' Perspectives1

With the 1996 introduction of a new visa making it easier for employers to sponsor skilled foreign workers, temporary skilled migration has become a significant component of international migration flows to Australia. This paper examines employers' reasons for sponsoring skilled workers from abroad, their modes of recruitment, the occupational skills they require, and their industry profile. We also discuss issues relating to the perception of a shortage of skilled workers, the extent that sponsoring foreign workers substitutes for investing in local training, and the role of networks in recruiting overseas workers. Many employers' now have a global view of labour recruitment. While this is understandable for multinational companies with global operations, many small businesses and public sector institutions are adopting the same strategy to obtain skilled labour which they say is in short supply in Australia. With the internationalization of the Australian economy, there is also an increasing demand for people with specialized skills and knowledge that is not available in Australia's relatively small labour market. An understanding of the demand factors motivating temporary skilled migration is crucial to effectively managing Australia's migration and labour trends.     

DETERMINANTS OF VOLUNTARY OVERTIME DECISIONS

This paper develops and estimates a model of the labor supply for overtime work when some workers' choices are constrained by mandatory overtime provisions of employers. Economic incentives are shown to have a significant effect on workers' overtime decisions. Policy simulations suggest that an increase in the overtime premium would lead to greater voluntary overtime work, as would a lowering of the level of weekly hours after which the mandatory premium takes effect. The estimated effects of these changes are not quantitatively large, indicating that workers are fairly insensitive to changes in monetary incentives in making overtime decisions.     

Local Produce,Foreign Labor: Labor Mobility Programs and Global Trade Competitiveness in Canada*

Abstract Temporary visa workers are increasingly taking on a heightened profile in Canada, entering the workforce each year in greater numbers than immigrant workers with labor mobility rights (Sharma 2006). This paper examines the incorporation of foreign workers in Canadian horticulture under the Seasonal Agricultural Workers Program (SAWP). I argue that foreign labor supplied under the SAWP secures a flexible workforce for employers and thus improves Canada's trade competitiveness in the global agrifood market. Using multiple research strategies, I track the evolution of Canadian horticulture in the global market and the transformation of labor in this industry. I outline the steady growth in the employment of temporary visa workers in the horticultural industry and show how they have become the preferred and, in some cases, core workforce for horticulture operations. The benefits of SAWP workers to employers include the provision of a workforce with limited rights relative to domestic workers and considerable administrative support in selecting, dispatching, and disciplining workers provided at no cost by labor supply countries. I conclude that the SAWP is a noteworthy example of the role of immigration policy in regulating the labor markets of high‐income economies and thus ensuring the position of labor‐receiving states within the global political economy.     

Manpower export and economic development: evidence from the Philippines

The Philippines has actively pursued a policy of labor export with the expectation that it would relieve unemployment, augment the supply of skills, and relieve pressure on the balance of payments. It was also anticipated that the inflow of overseas workers' remittances would translate into increased investment, the sine qua non for economic development. However, recent evidence casts some doubt on the extent to which these goals have been achieved. Particularly in the areas of skill formation, there appears to be a significant discrepancy between anticipated and actual outcomes. Indeed, it appears that the labor export may reduce the supply of skills available since 1) many skilled and educated workers are taking jobs requiring skill levels lower than they possess, and 2) a large majority of returning workers do not want to take up employment in those occupations reliant on the skills they used abroad. There is conflicting evidence regarding the impact of labor export on Philippine industries. There is some anecdotal evidence that a few industries have suffered because of a loss of key workers. In general, however, it appears that unemployment is still quite significant in those occupations most heavily represented in labor export. Despite this observation, it may still be true that labor emigration is selective of only the best workers, implying a decline in quality of the work force and possibly productivity in certain industries. The export of professional, technical, and managerial workers is another issue. Unless it can be shown that these workers are in excess supply, it is not advisable to expand the number going abroad. Although their salaries may be higher, and hence their remittances greater, their loss can impose costs on indigenous industries well in excess of a any marginal gains. Remittances from overseas workers do constitute a relatively significant source of foreign exchange. However, the translation of remittances into investment has been restrained by the very low propensity of remittance recipients and returnees to undertake productive investment and by the diversion of remittances from formal banking channels into informal channels. Remittances which are being channeled through the formal banking sector constitute a potentially important source of loan funds, as well as providing a potential stimulus to indigenous industry.     

Jacob Mincer and Labor Supply–Before and Aftermath

This paper discusses the impact that Jacob Mincer's 1962 paper Labor-Force Participation of Married Women... had on the analysis and empirical estimation of the labor supply of married women, and the supply of labor in general. It is argued that this paper has revolutionized the analysis of labor supply. The sharp increase in married women's labor supply still constitutes a challenge to labor economists who try to explain the phenomenon in terms of income and price effects derived from cross-section studies. It constituted a puzzle to labor economists in the 1950s and 1960s, still captives of the notion of a backwards-bending supply of labor. Mincer combined a theoretical model distinguishing between three uses of time (leisure, work at home, and work in the market) and Friedman's distinction between permanent and transitory earning. He showed that the wage has a positive effect on married women's labor supply, and that this supply is more affected by transitory than by permanent income changes. The new theory serves as the scaffold on which Mincer builds the empirical estimation. The interplay between theory, data, and empirical estimation, and the ingenuity of the empirical research using scant data sources, made this paper the object of emulation. The ideas first discussed in this paper generated many of the developments in the analysis of labor supply witnessed over the last four decades.     

Unauthorized workers and immigration reform: what can we ascertain from employers?

The Immigration Reform and Control Act of 1986 attempts to curb unauthorized migration by requiring employers to screen the authorizing documents of all workers. Many different documents may be used, with employers required to simply attest to the face validity of workers' documents upon an I-9 form. The authors report findings from their study estimating the unauthorized US labor force and exploring employers' initial reactions to the passage of the Immigration Reform and Control Act (IRCA) of 1986. The findings are based upon hiring practices information supplied by a sample of businesses in an evaluation of the IRCA impact. A selectivity correction model is used to impute 2.6 million unauthorized workers in the entire sample. The estimate, which compares favorably with other estimates, is tabulated by questions about IRCA. Findings suggest that a large proportion of the unauthorized labor force uses fraudulent documents, many without the knowledge of their employer. It appears that Immigration and Naturalization Service-targeted establishments hire 20% of unauthorized workers and that the employers of unauthorized workers are no more likely than other employers to believe that they can be sanctioned under IRCA. This may be associated with the apparent lack of marked change in patterns of unauthorized hiring in the period immediately following IRCA passage. There was some change in hiring behaviors in establishments hiring unauthorized workers, affecting wage offers and documentation, but US employers do not seem to perceive changes in the supply or availability of authorized workers. Study findings indicate only marginal IRCA-related changes in the characteristics of unauthorized hires during the very initial phase of IRCA's implementation. The combination of readily available fraudulent documents, the difficulty in detecting such documents, and the steady demand for low-skilled workers creates conditions which are not conducive to markedly changed hiring behavior.     

On-the-Job Search,Mismatch and Worker Heterogeneity

This paper empirically examines the search behavior of currently employed workers to understand changes in on-the-job search across different types of employed individuals and varying labor market conditions. Using data from the American Time Use Survey, we estimate the responsiveness of workers with varying levels of productivity and job-match quality to regional labor market conditions. We find that those workers who are less-productive, mismatched in their current position, and high-productivity, mismatched workers are more likely to engage in search than other workers. These results have implications for models built on job mismatch, as well as for models seeking to explain increasing inequality and wage dispersion.     

The demand for leisure time in the presence of constrained work hours

This article presents a labor supply model designed to address situations of overemployment or underemployment in the labor market. Previous labor supply models have taken the possibility of work hour constraints into consideration but typically assumed that the existence of fixed work hours only influenced the decision of labor force participation. This ignores situations in which individuals choose to be employed at fixed-hour jobs even though these jobs do not offer the desired work hours.     

Education as a social agreement

This article shows that the main hypotheses used in the economic literature to explain the existence of low-skill traps are not necessary. In particular, if we relax two strong assumptions, those of perfect information in the labor market and individual homogeneity, less-developed countries may remain caught in a poverty trap even when there are not intergenerational or intertemporal spillovers, intersectoral complementarities, increasing returns to scale or credit market imperfections. Due to the lack of coordination among workers, the role played by some institutions such as universities or unions in escaping the trap becomes crucial. A numerical calibration of the model supports our conclusions.     

COLLATERAL CONSTRAINTS AND THE CURRENT ACCOUNT: THEORY AND EVIDENCE

We investigate the impact of domestic financial frictions on the current account dynamics in Asian countries before and after the Asian financial crisis in 1997–1998 by introducing collateral constraints into the intertemporal current account approach. We examine six Asian countries. Before the crisis, collateral constraints significantly impact the current account in Korea, Malaysia, the Philippines, and Thailand, but after the crisis, they do not. Our study shows that the impact of domestic financial frictions on the current account changes before and after a financial crisis. (JEL F32, F41)     

Reshaping the social contract: emerging relations between the state and informal labor in India

As states grapple with the forces of liberalization and globalization, they are increasingly pulling back on earlier levels of welfare provision and rhetoric. This article examines how the eclipsing role of the state in labor protection has affected state–labor relations. In particular, it analyzes collective action strategies among India’s growing mass of informally employed workers, who do not receive secure wages or benefits from either the state or their employer. In response to the recent changes in state policies, I find that informal workers have had to alter their organizing strategies in ways that are reshaping the social contract between state and labor. Rather than demanding employers for workers’ benefits, they are making direct demands on the state for welfare benefits. To attain state attention, informal workers are using the rhetoric of citizenship rights to offer their unregulated labor and political support in return for state recognition of their work. Such recognition bestows informal workers with a degree of social legitimacy, thereby dignifying their discontent and bolstering their status as claim makers in their society. These findings offer a reformulated model of state–labor relations that focuses attention on the qualitative, rather than quantitative, nature of the nexus; encompasses a dynamic and inter-dependent conceptualization of state and labor; and accommodates the creative and diverse strategies of industrial relations being forged in the contemporary era.
