Labor Force Participation of Women in the EU – What Role do Family Policies Play?

We empirically study the role of different family policies in affecting women's labor market behavior in the European Union. Women tend to assume more family duties than men and, consequently, often participate less in the labor market. Family policies aim to support families in general while a particular focus is on helping women to reconcile family duties with labor market participation. Their impact, however, is not clear, especially when it comes to different forms of labor market activity. We use a static and dynamic panel econometric framework examining the link between financial support for four types of family policies and labor force participation as well as (part‐time and full‐time) employment. The results suggest no stable significant impact of expenditures on family policies on overall labor force participation. However, higher spending on family allowance, cash benefits, and daycare benefits appears to promote part‐time employment, whereas only spending on parental leave schemes is a significant positive determinant of women's full‐time employment.

The Effect of Legislated Minimum Wage Increases on Employment and Hours: A Dynamic Analysis

We present a dynamic policy simulation analysing what would have happened to wages, employment, and total hours had the federal minimum wage increased in September 1998, a year after the last actual increase in our data. Prior work suggests that employment responses take 6 years to play out. Using a time‐series model for 23 low‐wage industries, we find a positive response of average wages over 54 months following an increase in the minimum wage, but neither employment nor hours can be distinguished from random noise. Ignoring confidence intervals, the adjustment of hours is complete after 1 year, the adjustment of employment after no more than two and one half years.     

Women's Career Development and Divorce Risk in Japan

ABSTRACT In Japan, divorce rates have more than doubled since the mid-1960s, and female paid employment has increased rapidly in the past few decades. By applying a conventional economic model of labor force participation to micro-level data gathered from a nationally representative sample survey, this paper shows that Japanese married women who have contemplated divorcing their husbands are more likely to participate in the workforce as full-time paid employees. This finding suggests that an increasing risk of divorce has made a substantial contribution to the fast rise in Japanese women's participation in paid employment, particularly full-time work.     

Women’s Employment Status and Hours Employed in Urban Brazil: Does Husbands’ Presence Matter?

The determinants of hours worked for employed women in developing countries is a little‐studied topic. We compare the determinants of employment with the determinants of hours worked for prime‐aged urban Brazilian women with and without husbands present. Given employment status, we find systematic differences for women in couple‐headed and female‐headed households. For the former, the same variables that affect employment do a good job of explaining hours worked. In contrast, our model generally fails to capture determinants of variation in hours worked for women who are sole heads of households. Sample selectivity functions in opposite directions for the two groups.     

Female Labor Supply,Human Capital,and Welfare Reform

We estimate a dynamic model of employment, human capital accumulation—including education, and savings for women in the United Kingdom, exploiting tax and benefit reforms, and use it to analyze the effects of welfare policy. We find substantial elasticities for labor supply and particularly for lone mothers. Returns to experience, which are important in determining the longer‐term effects of policy, increase with education, but experience mainly accumulates when in full‐time employment. Tax credits are welfare improving in the U.K., increase lone‐mother labor supply and marginally reduce educational attainment, but the employment effects do not extend beyond the period of eligibility. Marginal increases in tax credits improve welfare more than equally costly increases in income support or tax cuts.     

Risk Aversion,Collective Bargaining,and Wages in Germany

We develop an open‐shop model of trade union membership in which workers differ in their risk attitudes, and derive conditions under which the bargained wage will fall and union membership will increase with a general rise in risk aversion. Using data from the German Socio‐Economic Panel we define broad bargaining units and show that wages decline as average risk aversion of union members in these units rises, controlling for individual effects of risk aversion. Given a negative relationship between wages and employment, this suggests that secular changes in risk attitudes, because of an aging workforce or greater female labour force participation, can help to explain variations in the employment performance of unionized economies.     

Employment Decisions of Married Women: Evidence and Explanations

Aggregate evidence has revealed a significant increase in women’s labour market participation (especially among married women) and a decline in male participation, both in Italy and in all the other OECD countries. This paper empirically tests the relationship between the education and employment status of husbands and wives using the Bank of Italy Survey (1995). The results of our analysis show that employed women are likely to be married to employed men with a higher level of education and higher income. The estimates of the labour supply decisions of wives show that the effect of the unemployment status of husbands is mediated by other factors associated with the family’s view of wives working outside home. The response to a husband’s unemployment depends significantly on the employment decisions of parents (mothers and mothers‐in‐law), a proxy for the couple’s attitude towards women’s work.     

A Model of the Consumption Response to Fiscal Stimulus Payments

A wide body of empirical evidence finds that approximately 25 percent of fiscal stimulus payments (e.g., tax rebates) are spent on nondurable household consumption in the quarter that they are received. To interpret this fact, we develop a structural economic model where households can hold two assets: a low‐return liquid asset (e.g., cash, checking account) and a high‐return illiquid asset that carries a transaction cost (e.g., housing, retirement account). The optimal life‐cycle pattern of portfolio choice implies that many households in the model are “wealthy hand‐to‐mouth”: they hold little or no liquid wealth despite owning sizable quantities of illiquid assets. Therefore, they display large propensities to consume out of additional transitory income, and small propensities to consume out of news about future income. We document the existence of such households in data from the Survey of Consumer Finances. A version of the model parameterized to the 2001 tax rebate episode yields consumption responses to fiscal stimulus payments that are in line with the evidence, and an order of magnitude larger than in the standard “one‐asset” framework. The model's nonlinearities with respect to the rebate size and the prevailing aggregate economic conditions have implications for policy design.     

A Theory of the Firm with Non‐binding Employment Contracts

This paper examines an employment relation in which individual workers enjoy some bargaining power vis‐a‐vis the firm although they are not unionized. The main elements of the situations studied here are that the employment contracts are non‐binding across periods of production and that the firm has opportunities to replace workers. The paper analyzes a dynamic model in which the processes of contracting and recontracting between the firm and its workers are intertwined with the dynamic evolution of the firm's workforce. The analysis of the model is somewhat complicated because the employment level is a nondegenerate state variable that evolves over time and is affected by past decisions. The main analytical results characterize certain important equilibria: the profit maximizing and stationary equilibria. The unique stationary equilibrium is markedly inefficient: it exhibits inefficient over‐employment and the steady state wages coincide with the workers' reservation wage. It confirms earlier results derived by Stole and Zwiebel (1996a, b) in the context of a static model and shows that they are very robust even when the firm has nearly frictionless hiring opportunities. In contrast, in the profit maximizing equilibrium the outcome is nearly efficient and the wage exhibits a mark‐up over the reservation wage.     

Integrating Household Risk Mitigation Behavior in Flood Risk Analysis: An Agent‐Based Model Approach

Recent studies showed that climate change and socioeconomic trends are expected to increase flood risks in many regions. However, in these studies, human behavior is commonly assumed to be constant, which neglects interaction and feedback loops between human and environmental systems. This neglect of human adaptation leads to a misrepresentation of flood risk. This article presents an agent‐based model that incorporates human decision making in flood risk analysis. In particular, household investments in loss‐reducing measures are examined under three economic decision models: (1) expected utility theory, which is the traditional economic model of rational agents; (2) prospect theory, which takes account of bounded rationality; and (3) a prospect theory model, which accounts for changing risk perceptions and social interactions through a process of Bayesian updating. We show that neglecting human behavior in flood risk assessment studies can result in a considerable misestimation of future flood risk, which is in our case study an overestimation of a factor two. Furthermore, we show how behavior models can support flood risk analysis under different behavioral assumptions, illustrating the need to include the dynamic adaptive human behavior of, for instance, households, insurers, and governments. The method presented here provides a solid basis for exploring human behavior and the resulting flood risk with respect to low‐probability/high‐impact risks.     

The Gender Wage Gap and Poverty in Colombia

Abstract. Using 19 years of cross‐section wage data, we look at the trend of the ratio of male to female wages in Colombia. First, we observe a long‐term trend towards an increase in the gender wage gap that may be related to new labor regulations giving more protection to women and thereby raising the cost of female employment for firms. Second, we measure the impact on poverty of the increasing gap by producing estimates of the income distribution for the subsequent years had the wage gap remained at the low level it used to be in the early 1990s. As mainly low‐skilled women suffered from the increase in the wage gap, we find that the phenomenon contributed to an overall increase in poverty during the decade.     

Employment Transitions after Motherhood in Spain

Abstract. This paper investigates transitions from employment to non‐employment and downward occupational mobility after motherhood in Spain. Around 40 per cent of Spanish women who were at work 1 year before childbearing leave employment, most permanently, and one‐third of these exits move to unemployment. The probability of staying on at work after birth is reduced with the rise of fixed‐term contracts and increased with experience and level of education. Downward occupational mobility is not common amongst women remaining employed since they do not switch to part‐time jobs.     

RISK SHARING WITH LIMITED COMMITMENT AND PREFERENCE HETEROGENEITY: STRUCTURAL ESTIMATION AND TESTING

In order to analyze the role of limited commitment and preference heterogeneity in explaining the consumption allocation, I propose a theoretical and empirical framework to estimate and evaluate a risk‐sharing model where insurance transfers have to be self‐enforcing and the coefficient of relative risk aversion may depend on observable household characteristics. I compare this model to benchmark models with full commitment and/or without preference heterogeneity using data from three Indian villages. I find that the limited commitment model with heterogeneous preferences outperforms the benchmark models in a statistical sense and in terms of (i) explaining the dynamic response of consumption to idiosyncratic income shocks, (ii) accounting for the variation of consumption unexplained by household and time effects, and (iii) capturing the variation of inequality across time and villages and predicting changes in inequality. I also use the estimated models to predict the effects of a counterfactual tax and transfer policy on the consumption allocation. The limited commitment model with preference heterogeneity predicts larger benefits to the poor than its homogeneous counterpart. (JEL: C52, D10, D52)     

Dynamic Effects of the Minimum Wage on Informality in Colombia

Informality is a common phenomenon in developing countries and is not uncommon in industrialized societies. Although persistent aggregate rates of informal employment for a certain period of time may be indicative of low rates of employment status change among individuals, more intensive studies regarding persistent individual informal employment are needed. We used a reduced‐form dynamic pseudo panel data model approach that accounted for unobserved heterogeneity and initial conditions to present empirical evidence of the extent of persistent informality in a developing country, where education is the primary force of mitigating permanent informality. Using data from Colombia, we also provide results on the complex effect of minimum wage levels on informality. An increase in the minimum wage resulted in increased informality and increased the persistence of informality. Our results may be a basis with which to discuss the persistence of informality in other developing countries.     

Is There a Double‐Negative Effect? Gender and Ethnic Wage Differentials in Italy

This paper investigates the gender and ethnic wage differentials for female migrants in Italy by applying the Oaxaca–Blinder decomposition, with and without Heckman correction, to account for self‐selection into the labour market. The gender wage gap is nearly 15 per cent, more than 60 per cent of which is unexplained by observable differences. The ethnic wage gap is much larger (39 per cent), but endowments explain 53 per cent of the gap. We also estimate the double‐negative effect of being both female and a migrant. A female migrant earns 42 per cent less than an Italian male; the unexplained component is estimated to be 53–65 per cent. Results are robust to different specifications.     

Learning‐by‐Doing,Organizational Forgetting,and Industry Dynamics

Learning‐by‐doing and organizational forgetting are empirically important in a variety of industrial settings. This paper provides a general model of dynamic competition that accounts for these fundamentals and shows how they shape industry structure and dynamics. We show that forgetting does not simply negate learning. Rather, they are distinct economic forces that interact in subtle ways to produce a great variety of pricing behaviors and industry dynamics. In particular, a model with learning and forgetting can give rise to aggressive pricing behavior, varying degrees of long‐run industry concentration ranging from moderate leadership to absolute dominance, and multiple equilibria.     

DO MARKETS RESPOND MORE TO MORE RELIABLE LABOR MARKET DATA? A TEST OF MARKET RATIONALITY

Since 1979, the Bureau of Labor Statistics (BLS) has nearly quadrupled the size of the sample used to estimate monthly employment changes. Although first‐reported employment estimates are still noisy, the magnitude of sampling variability has declined in proportion to the increase in the sample size. A model of rational Bayesian updating predicts that investors would assign more weight to the BLS employment survey as it became more precise. However, a regression analysis of changes in interest rates on the day the employment data are released finds no evidence that the bond market's reaction to employment news intensified in the late 1980s or 1990s; indeed, in the late 1990s and early 2000s the bond markets hardly reacted to unexpected employment news. For the time period as a whole, an unexpected increase of 200,000 jobs is associated with about a 6 basis point increase in the interest rate on 30‐year Treasury bonds, and an 8 basis point increase in the interest rate on three‐month bills, all else equal. Additionally, unexpected changes in the unemployment rate and revisions to past months' employment estimates have statistically insignificant effects on long‐term interest rates.

A Dynamic Model of Demand for Houses and Neighborhoods

This paper develops a dynamic model of neighborhood choice along with a computationally light multi‐step estimator. The proposed empirical framework captures observed and unobserved preference heterogeneity across households and locations in a flexible way. We estimate the model using a newly assembled data set that matches demographic information from mortgage applications to the universe of housing transactions in the San Francisco Bay Area from 1994 to 2004. The results provide the first estimates of the marginal willingness to pay for several non‐marketed amenities—neighborhood air pollution, violent crime, and racial composition—in a dynamic framework. Comparing these estimates with those from a static version of the model highlights several important biases that arise when dynamic considerations are ignored.     

Measuring the Implications of Sales and Consumer Inventory Behavior

Temporary price reductions (sales) are common for many goods and naturally result in large increases in the quantity sold. Demand estimation based on temporary price reductions may mismeasure the long‐run responsiveness to prices. In this paper we quantify the extent of the problem and assess its economic implications. We structurally estimate a dynamic model of consumer choice using two years of scanner data on the purchasing behavior of a panel of households. The results suggest that static demand estimates, which neglect dynamics, (i) overestimate own‐price elasticities by 30 percent, (ii) underestimate cross‐price elasticities by up to a factor of 5, and (iii) overestimate the substitution to the no‐purchase or outside option by over 200 percent. This suggests that policy analysis based on static elasticity estimates will underestimate price–cost margins and underpredict the effects of mergers.
