INFLATION DYNAMICS AND LABOR MARKET SPECIFICATIONS: A BAYESIAN DYNAMIC STOCHASTIC GENERAL EQUILIBRIUM APPROACH FOR JAPAN'S ECONOMY

Which labor market specification is better able to describe inflation dynamics, a widely used sticky wage model or a recently investigated labor market search model? Using a Bayesian likelihood approach, we estimate these two models with Japan's data. This article shows that the labor market search model is superior to the sticky wage model in terms of both marginal likelihood and out‐of‐sample forecast performance, particularly regarding inflation. The labor market search model is better able to replicate the cross‐correlation among inflation, real wages, and output in the data. Moreover, in this model, real marginal cost is determined by both hiring cost and unit labor cost that varies with employment fluctuations, which gives rise to a high contemporaneous correlation between inflation and real marginal cost as represented in the New Keynesian Phillips curve.

LABOR MARKET OPENNESS,H‐1B VISA POLICY,AND THE SCALE OF INTERNATIONAL STUDENT ENROLLMENT IN THE UNITED STATES

International students have long comprised an important part of U.S. higher education. However, little is known regarding the factors that encourage students from across the world to enroll in U.S. colleges and universities each year. This paper examines the relationship between international enrollment and the openness of the United States' skilled labor market, currently regulated by the H‐1B program. Gravity regressions reveal that H‐1B visa issuances to a country are positively and significantly related to the number of international students from that country. Causal estimates of the impact of labor market openness are achieved by exploiting a dramatic fall in the H‐1B visa cap in October 2003. Triple difference estimates show that the fall in the cap lowered foreign enrollment by 10%. (JEL F22, I21, J11)     

GEOGRAPHIC DIFFERENCES IN U.S. UNEMPLOYMENT RATES: A VARIANCE DECOMPOSITION APPROACH

This paper analyzes the determinants of the geographic dispersion of unemployment rates. The model presented here recognizes that structural labor market relationships differ across areas and that area unemployment rates and some of the explanatory variables are determined simultaneously. Most importantly, the methodology introduced here provides an estimate of the impact of each of the explanatory variables on the overall dispersion of unemployment rates, allowing comparison of several competing hypotheses that purport to explain why areas differ so widely in terms of their unemployment rates. The empirical results indicate that inter-area differences in product market demand and in sensitivity to changes in conditions in the product market are the most important factors accounting for geographic differences in unemployment rates. More generally, the results indicate that unemployment rates differ widely across areas not so much because areas differ in terms of the underlying characteristics that determine unemployment rates but because areas are so heterogeneous with respect to labor market structure.     

Unemployment: A labor market perspective

Twentieth century economists have made countless attempts to resolve the causes and cures of unemployment. However none have ventured to consider unemployment not as a social problem but as a market response to political and economic incentives. By treating unemployment as a labor market, where workers rationally select periods of joblessness and where special interest groups profit from unemployment, this paper develops a theoretically consistent model to explain the effects that policy and economic variables have on unemployment. Empirical results support this approach and the worker disincentive effects of UI compensation by estimating simultaneously a demand and supply for unemployment.     

STRUCTURAL UNEMPLOYMENT IN THE UNITED STATES: THE EFFECTS OF INTERINDUSTRY and INTERREGIONAL DISPERSION

The effects of sectoral shifts, measured by dispersion in the growth rates of employment or earning across industries or regions, on unemployment are tested in a specification controlling for the effects of other labor-market variables and shifts in the demographic composition of the labor force. Interindustry and geographical shifts in labor demand have significant unemployment effects, with adult males the group most strongly affected. The estimated equations imply that most of the fluctuation in unemployment over the period 1956-87 was been due to microeconomic causes rather than aggregate demand.     

PRODUCT DIVERSITY,DEMAND STRUCTURES,AND OPTIMAL TAXATION

This article studies optimal taxation in a general equilibrium macroeconomic model with endogenous entry. We compare the constant elasticity of substitution (CES) model to three alternative demand structures: oligopolistic competition in prices, oligopolistic competition in quantities, and translog preferences. Our economy is characterized by two distortions: a labor distortion due to the misalignment of markups on goods and leisure, and an entry distortion due to the misalignment of the consumer surplus effect and the profit destruction effect of entry. The two distortions interact in determining the wedge between the market‐driven and optimal level of product diversity. We show how optimal labor and entry taxes depend on the prevailing demand structure, the nature and size of entry costs, and the degree of substitutability between goods. (JEL E22, E61, E62)     

BUSINESS CYCLE FLUCTUATIONS WITH THE DIVISION OF PERMANENT AND TEMPORARY EMPLOYMENT

In the mainstream real business cycle (RBC) model, labor can be viewed as temporary employment since the firm's demand for labor behaves directly in response to stochastic productivity shocks in each period. This paper provides a tractable way of analyzing fluctuations in permanent and temporary employment over the business cycle, as well as the underlying driving forces. This inclusion of heterogeneity helps reconcile the RBC model with the U.S. data given that temporary employees in general only account for a small proportion of total private‐sector employment (about 2%–3%). We draw an explicit division between permanent and temporary employment and resort to this separation to account for stylized facts that characterize a two‐tier labor market. In particular, with regard to the U.S. labor market, our benchmark model can well explain the motivating facts: (1) temporary employment is much more volatile than permanent employment, (2) the share of temporary employment (the ratio of temporary to aggregate employment) exhibits strong pro‐cyclicality, (3) permanent employment lags by two quarters on average, and (4) the correlation between temporary employment and output is stronger than that involving the permanent counterpart. The quantitative analysis suggests that our proposed channels explain the main facts well and the model further provides plausible reasoning for a firm's labor hoarding. (JEL E24, E32)     

Financial Market Variables do not Predict Real Activity: Further Evidence

Previous studies argue that financial variables do not help forecast U.S. output growth. F statistics for excluding financial variables from output growth equations depend on the sample period and the inclusion of 1974:12 in the sample. Also, an autoregressive model of output growth often provides better forecasts than models with lagged financial variables included. I decompose output into permanent and cyclical components and ask whether financial variables help forecast either component in isolation. The paper‐bill spread does improve in‐sample forecasts of cyclical output, but no financial variable helps forecast either cyclical output or permanent output growth out of sample.     

Effects of positive attitude and optimism on employment: Evidence from the US data

Using samples from the National Longitudinal Survey of Youth (NLSY) and following a bivariate probit approach, the current study estimates the worker's employment probability equations in both cross-sectional and panel data frameworks. The study demonstrates that the employment of the worker, which depends on both the worker's labor market participation decision and the employer's hiring decision, is determined partly by the positive and optimistic attitude of the worker. The effects of these attitude variables on both decisions are even larger than the effects of standard human capital variables. The study further demonstrates that the attitude variables affect employment probabilities of men and women differently because their effects on participation and hiring decisions are different.     

Studienmotivation, Erwerbspartizipation und der Einstieg in den Arbeitsmarkt

Increased student enrollment in public universities has led to a debate on curricula reform with a view to limiting the length of study, particularly by introducing tuition fees for long-time students. It is implicitly assumed in this debate that all students are full-time students. We investigate why and to what extent students participate in the labor market. Furthermore, we study the effects of part-time work on the time it takes to graduate, to find employment and on the level of earnings. We analyze two data sets, first, a survey among students enrolled at the University of Bern conducted during summer 2001 (N = 3360) and secondly, a survey of all university graduates in Switzerland conducted in 2001 (N = 7005). The results show that labor market participation increases the time it takes students to reach graduation. However, labor market experience reduces the time it takes graduates to find employment and increases their earnings by 4 percent if their experience was related to the subject being studied. Labor market participation bearing no relation to university studies has no negative effects on graduate entrance into the labor market. Thus, the study suggests that student participation in the labor market has more beneficial effects than disadvantages. In light of these results curricula reforms should take into account the possibility of gaining labor market experience.     

Economic Theories of Low-Wage Work

This article examines economic theories of the low-wage labor market to increase understanding of economic inequality and poverty in the United States, particularly related to the labor market. On the one hand, neoclassical, labor monopsony, and Harris-Todaro models explain how minimum wage policies are related to supply and demand of labor, human capital, employment, and unemployment. On the other hand, the efficiency wage model, the dual labor market theory, and technology development and globalization account for the causes of the wage differentials. This article includes a conceptual map that illustrates the interrelationships between these economic theories of low-wage work.     

LABOR CONTRACTS AND FLEXIBILITY: EVIDENCE FROM A LABOR MARKET REFORM IN SPAIN

This paper evaluates the effects of a labor market reform in Spain that removed restrictions on fixed‐term or temporary contracts. Our empirical results are based on longitudinal firm‐level data that cover observations before and after the reform. We posit and estimate a dynamic labor demand model with indefinite and fixed‐term labor contracts, and a general structure of labor adjustment costs. Experiments using the estimated model show important positive effects of the reform on total employment (i.e., a 3.5% increase) and job turnover. There is a strong substitution of permanent by temporary workers (i.e., a 10% decline in permanent employment). The effects on labor productivity and the value of firms are very small. In contrast, a counterfactual reform that halved all firing costs would produce the same employment increase as the actual reform, but much larger improvements in productivity and in the value of firms.

THE U.S. LABOR INCOME SHARE AND AUTOMATION SHOCKS

The causes and consequences of the 1964–2016 swings in the U.S. labor income share/labor share (LS) are parsed through the lens of a structural model estimated on aggregate and LS series jointly. Where conventional models fall short, the present model yields a counter-cyclical LS unconditionally and in response to demand and monetary policy shocks, as well as a small wage pro-cyclicality, via moderate wage indexation. Shifts in automation, workers' market power, investment efficiency, and the relative price of investment account for 54%, 24%, 6%, and 4% of LS fluctuations, respectively. Automation shocks explain the lion's share of the post-2007 cyclical LS tumble and 11% of output cycles, and generate a distinctive counter-cyclical labor response. (JEL E32, E25, E52)     

Les transformations du marché du travail : un éclairage à partir de l’analyse des décalages entre offre et demande dans un système productif localisé

This new look at approaches to the labor market emphasizes that changes observed during the past twenty years are related to trends as much in supply as in demand. Analyzing both these sides is shown to be valuable for understanding the impact on labor market trends and shedding light on the tensions and contradictions between supply and demand. The mechanisms that have come into play during this period are analyzed in a local productive system, namely agribusiness in the lower Rhone valley in the Provence-Alpes-Côte d’Azur Region of France.     

LIFETIME CONSUMPTION, LABOR SUPPLY AND FERTILITY: A COMPLETE DEMAND SYSTEM

This paper applies an empirical method based on a complete demand system to the study of lifetime consumption, labor supply and fertility. Previous research in this area has not used complete demand systems or rigorously connected empirical analysis with the theoretical model. An approach to estimating crucial but unmeasured variables is proposed. The results are generally supportive of a price-income effects model.     

IDENTIFYING THE ROLE OF RISK SHOCKS IN THE BUSINESS CYCLE USING STOCK PRICE DATA

I analyze the sources of U.S. business cycle fluctuations in an estimated Dynamic Stochastic General Equilibrium model with a rich set of nominal and real rigidities and various exogenous disturbances. The model includes a shock to the expected risk‐premium, which introduces a time‐varying wedge between the policy rate set by the central bank and the cost‐of‐capital of firms. In the aggregate data, most U.S. corporations finance their investment using internal funds, and stock prices reveal the opportunity cost of this type of financing. I therefore use corporate market value and dividend data in the Bayesian estimation of the model to identify risk shocks. Variance decomposition exercises show that these shocks account for a substantial part of the variation in the stock market, as well as the variation in output and investment, especially at short forecast horizons. The variation of these variables at longer forecast horizons are mainly captured by shocks to investment‐specific technological change. Historical decomposition points to the important role played by risk shocks in the run up of stock prices and output in the late 90s, and in the reversal of these variables in the early 2000s and during the recent recession.

Municipal residency laws: Effects on police employment,compensation, and productivity

This paper offers an alternative model of the effects of residency laws in municipal labor markets. Unlike previous studies, the model assumes that public employee labor markets are characterized by conditions of excess supply and that public services are produced under noncompetitive conditions. The model also implies that productivity improvements increase rather than reduce labor demand, yielding different results with respect to the wage and employment effects of residency requirements. The non-clearing market model is tested using data on municipal police officers. The results are more compatible with the disequilibrium model than with models based on a competitive equilibrium.     

THE PHYSICIAN LABOR MARKET IN A MANAGED CARE-DOMINATED ENVIRONMENT

The belief that doctors respond to declining demand by treating patients more aggressively has created skepticism about relying on market forces to restructure physician supply. We argue that even if the physician labor market is dysfunctional under fee-for-service incentives, it can perform better as managed care becomes dominant. Our model implies a nonlinear effect of managed care penetration on incomes. Physicians can offset most or all of initial declines in demand, but cannot insulate themselves indefinitely. This may explain the observation that, until recently, the growth of managed care has not been accompanied by large physician income changes. ( JEL III, J31)
