A TEST OF EMPLOYER DISCRIMINATION IN THE NBA

This paper presents a test of an important implication of Becker's theory of employer discrimination: when institutional change enhances labor mobility, employer discrimination falls because it becomes more costly for employers to indulge tastes for discrimination. The test case is the National Basketball Association (NBA). This paper specifically addresses the following question about the NBA: why did black/white player salary differentials vanish by the early 1990s? Previous studies claim that NBA wage gaps in the 1980s are attributable to customer discrimination and monopsonistic wage discrimination. This study argues that employer discrimination was an important source of those gaps and that one reason they vanished was because reduced monopsony power eradicated employer discrimination. Monopsony power fell because the 1988 NBA Collective Bargaining Agreement and the entry of four new teams in the league enhanced player mobility and increased the amount of labor market competition. Using data for the 1985-86 and 1990-91 seasons, employer discrimination was proxied by the race of the team's general manager. Empirical results strongly suggest that a major reason the NBA wage gap vanished in the later period was because of a reduction in employers' ability to discriminate. This is in contrast to earlier literature on the NBA, which has tended to emphasize the role of customer discrimination. (JEL J71)     

Parameter uncertainty and inflation dynamics in a model with asymmetric central bank preferences

This paper builds on the Lucas' (1973) signal extraction model to study the time-varying effect of uncertainty in the output-inflation trade-off on inflation, using a monetary model with asymmetric central bank preferences whereby deviations of output (relative to target) from above are weighted differently from deviations from below. The model is investigated empirically using data from the South African Reserve Bank (SARB). We show that the implication of the uncertainty element is to cause the authority to change its indirect control, output by less (and hence change it direct control, interest rate by less) whenever inflation is below or above the target, in line with Brainard's attenuation principle. We also find that SARB's asymmetric output stabilization explains inflation movements significantly, and that the monetary authority seems to be more averse to business cycle recessions than expansions, hence more keen to avoid recessions than expansions. Overall, a more transparent and committed monetary policy practice that would reduce uncertainty over the output-inflation trade-off would be helpful for economic stability.     

Uncertainty,inequality and consumption preferences in urban China

In this paper we present an uncertainty–inequality–consumption model and empirically investigate the effect of uncertainty on the consumption behaviors of urban households with varying levels of socio-economic status in China. We observe that the condition of households that suffered from socio-economic inequality with respect to total consumption, educational expenditures, medical expenditures, and durable consumption worsened relative to other households when faced with income uncertainty. Income uncertainty did not affect the housing consumption of households that suffered from socio-economic inequality, but it substantially decreased their ability to consume other durables. As a result of the introduction of the modern enterprise system and the reform of the housing distribution system, households with a member employed in a management position suffer larger shocks of income uncertainty in total consumption, educational expenditures, medical expenditures, and housing consumption relative to household with all members employed in worker positions in 2002. Uncertainty with respect to medical and educational expenditures had more substantial effects on the non-durables consumption of low-income households than that of other households in 2002.     

Employment expectations and uncertainties ahead of the new German minimum wage

This article analyzes announcement effects of the new statutory minimum wage on employment expectations and uncertainties in Germany. Using a difference‐in‐differences approach applied to the IAB Establishment Panel, employers affected by the minimum wage show an increased employment uncertainty and a 0.9% points drop in their expected employment growth. Using the same identification strategy with data from 2015, the treatment effect on actual employment growth of affected employers matches the employers' expectation. Hence, an analysis of employer expectations seems to be promising to detect employment effects of policy changes before they come into force.     

Uncertainty and the Timing of Automobile Purchases

Earlier studies have shown that lumpy investment models well characterize individual expenditures on durables, in particular automobiles. In this class of models, a higher level of uncertainty generally implies that the household should tolerate a larger imbalance between the actual stock of the durable and the target stock before adjusting it by buying and/or selling. Then, if the level of uncertainty increases, aggregate expenditures would temporarily fall. This hypothesis is tested by estimating an aggregate lumpy investment model on automobile expenditure data, using stock market volatility to proxy uncertainty. The result is that expenditures fall significantly as stock market volatility increases.     

Belief flipping in a dynamic model of statistical discrimination

The literature on statistical discrimination shows that ex-ante identical groups may be differentially treated in discriminatory equilibria. This paper constructs a dynamic model of statistical discrimination and explores what happens to the individuals who nonetheless overcome the initial discrimination. If an employer discriminates against a group of workers in her initial hiring, she may actually favor the successful members of that group when she promotes from within the firm. The worker's welfare implications (i.e. who benefits from an employer's discriminatory hiring practices) are unclear. Even though agents face discrimination initially, some may be better off because of it.     

Exporting and labour demand: Micro‐level evidence from Germany

It is widely believed that globalization increases the extent of employment and wage responses to economic shocks. In this paper, we investigate the effect of firms’ exporting activities on the wage elasticity of labour demand. Using rich, administrative linked employer–employee panel data from Germany and destination‐specific industry‐level information on trade flows, we explicitly control for self‐selection into exporting and endogeneity concerns. Overall, we find that exporting has a significant positive effect on the (absolute value of the) unconditional wage elasticity of labour demand. In line with our hypothesis, we further show that the effect is particularly strong for those plants that export a significant share of their output to low‐ and medium‐income countries, hence face relatively more price‐elastic product demand.     

Non-farm Income and Consumption Expenditures in Rural Bangladesh: Empirical Evidence from Multilevel Regression Modelling

This study examines the effects of non-farm income on household consumption expenditures in rural Bangladesh. A two-stage endogenous treatment effect model is built on data from a nationally representative Household Income Expenditure Survey (HIES) 2010 to control selection bias. The HIES follows a hierarchical data structure because the survey is based on two-stage stratified sampling. A multilevel mixed-effects linear regression model is used to capture the unobserved heterogeneity between clusters (PSUs) along with revealing important factors. Results reveal that non-farm income has a significant positive effect on household’s consumption expenditures and non-farm income recipient households spend about 29% more than their counterparts. In addition, higher level of per capita income, education, smaller family size and lower dependency ratio are found to be more effective in increasing consumption expenditures of rural households. Significant cluster-level variations are observed in the analyses. This study recommends that non-farm income generating activities should be encouraged among rural households as this would raise their consumption expenditures and hence, improve welfare and living standards among them.

     

Is ethnic discrimination due to distaste or statistics?

Employing a vignette experiment, we test the empirical importance of key attitudes underlying the models of taste-based and statistical discrimination in explaining ethnic hiring discrimination. We find that employer concern that co-workers and customers prefer collaborating with natives drives discrimination.     

Managerial flexibility, uncertainty, and corporate investment: The real options effect

This paper examines how changes in uncertainty affect corporate investment and how managerial flexibility influences this effect. Consistent with existing evidence, this study shows that increased uncertainty reduces a firm's capital expenditures even after controlling for investment opportunities and fund availability. It further shows that the negative effect of increased uncertainty on corporate investment is more pronounced for firms with fewer financial constraints and larger size. Overall, the results suggest that managerial flexibility proxied by certain firm characteristics affects the negative relation between uncertainty and investment.     

Recruitment channel use and applicant arrival: An empirical analysis

This paper focuses on the recruitment behaviour of firms at the extensive margin; we empirically explore the relationship between employer search strategies and the number of applicants by means of (reduced form) two-equations simultaneous models. The empirical analysis is carried out on a rich micro data set on Dutch employer recruitment behaviour. Our empirical analysis reveals that the economic conditions prevailing on the labour market influence employer search activity at the extensive margin. In particular, we see that in tight (slack) labour markets characterised by excess demand (supply) of labour, the flow of applicants is smaller (larger). Employers react to the shortage (excess) of applicants by using more (less) often advertisements. This recruitment channel appears to trigger a significantly larger flow of applicants.

Investment Under Monetary Uncertainty: A Panel Data Investigation

There is a presumption in the literature that price or exchange rate uncertainty, or uncertainty in the monetary conditions underlying them, will have a negative effect on investment. Some argue that this negative effect will be extended by imperfect competition. However, models of irreversible investment show that the situation is more complicated than that. In these models, investment expenditures are affected by the scrapping price available on world markets and also by the opportunity cost of waiting rather than investing. The impact of uncertainty is therefore going to depend on the type of industry and hence on the industrial structure of the economy concerned. In addition, it may depend on the persistence of any price misalignments away from competitive equilibrium. In this paper, we put these theoretical predictions to the test. We estimate investment equations for 13 different industries using data for nine OECD countries over the period 1970–2000. We find that the impact of price uncertainty is negative or insignificant in all but one case whereas the impact of (nominal) exchange rate uncertainty is negative in only six cases, positive in four cases, and insignificant in three others. In addition, there are conflicting effects from the real exchange rate. The net effect depends on whether the source of the uncertainty is in domestic markets or in foreign markets.     

Efficiency of Screening and Labor Income Inequality

We analyze the importance of information about individual skills for understanding human capital accumulation and income inequality. The paper uses the framework of an overlapping generations economy with endogenous investment in human capital. Agents in each generation differ by random individual ability, or talent, which affects the screening process. The human capital of an agent depends on both his talent and his investment in education. The investment decision is based on a public signal (test outcome), which screens all agents for their talents. We analyze how a better information system, which allows more efficient screening, affects investment in education and, hence, income inequality in equilibrium. As a main result, we find that, typically, less inequality in the distribution of actual incomes can only be achieved at the expense of more inequality in the distribution of income opportunities.     

Uncertain Medical Expenses and Precautionary Saving Near the End of the Life Cycle

This paper introduces a dynamic, structural model of household consumption decisions in which elderly families consider the effects of uncertain future medical expenses when deciding current levels of consumption. The model with uncertain medical expenses implies a potentially important role for precautionary saving incentives to explain slow rates of dissaving among elderly Americans during retirement. Rather than just simulating the stochastic dynamic model, preference parameters are estimated using panel data on health, wealth and expenditures for retired families. The health uncertainty model predicts consumption levels closer to observed expenditures than a life cycle model with uncertain longevity. However, elderly families typically dissave their financial assets more slowly than even the baseline health uncertainty model predicts is optimal.     

FISCAL EXPANSIONS,UNEMPLOYMENT, AND LABOR FORCE PARTICIPATION: THEORY AND EVIDENCE*

Structural VARs indicate that for many OECD countries labor force participation, employment, and the unemployment rate significantly increase following increases in government expenditures under a variety of specifications and identification schemes. Fiscal expansions also tend to increase real wages. Existing models have difficulties in generating such responses. We show that the empirical regularities can be reproduced with two additions into a standard New Keynesian model with matching frictions: (a) a labor force participation choice and (b) workers’ heterogeneity.     

Inflation Targeting: Some Extensions

Previous analyses of the implementation of inflation targeting are extended to monetary policy responses to different shocks, consequences of model uncertainty, and effects of interest rate smoothing and stabilization. Model uncertainty, output stabilization, and interest rate stabilization or smoothing all call for a more gradual adjustment of the conditional inflation forecast toward the inflation target. The conditional inflation forecast is the natural intermediate target during inflation targeting. The optimal way of reacting to shocks is hence to check how they affect the inflation forecast and then take the appropriate action.

FUNCTIONAL ESTIMATES OF JAPANESE GOVERNMENT DOMESTIC EXPENDITURES, FISCAL 1952–1963

The purpose of the paper is to describe current and constant price estimates of Japanese central and local government postwar domestic expenditures by economic type and function recently completed by Miss Yoshiko Kido, International Christian University, Tokyo, and myself. The rationale of the functional classification is to estimate those government expenditures which enhance the economy's productive capacity. Expenditures are divided into four broad functional categories: developmental, disaster repair and prevention, social welfare, and general government. These four categories are subdivided to two levels of disaggregation. We were able to break down government fixed investment, government enterprise inventory investment, current domestic transfers and subsidies into 42 functional components. For constant price series, each functional component by economic type was deflated by separate price indexes. We followed the Economic Planning Agency's procedure for the official national accounts of assuming no productivity change in the provision of government services. Our results are generally comparable to the official national accounts estimates. The major difference is that we attribute considerably more fixed investment to local governments, and correspondingly less to the central level. Government expenditures had the following characteristics. Growth was rapid; in real terms the public sector use of the economy's resources in 1963 was 2.2 times more than in 1952. The elasticity of government expenditures to GNP was unity in current prices, slightly less in real terms. The government postwar share in GNP has been smaller than in European nations and, unlike them, was not rising. This reflects the underlying growth strategy of emphasis upon private business fixed investment. Government consumption expenditures declined relative to GNP, and investment rose. Developmental expenditures comprised the largest share (40–45 per cent) of the government total. The elasticities to GNP of government expenditures by economic and functional categories are provided and discussed. A simple test was made of the cyclical relationship of government expenditures (both total and by category) to GNP. The results suggest that government expenditures, rather than contra-cyclical, were pro-cyclical in effect.     

Optimal design of pension funds: a mission impossible?

Summary. Nowadays many employers offer their employees the possibility of an insurance against too large losses in income when retiring or becoming disabled. This paper models the optimization problem of the employer when setting up such a so-called pension fund. Not surprisingly, it turns out that the optimal solution depends on the premium the employees are willing to pay at most for such an insurance. Since this is private information for an employee and hence not known to the employer, he needs to collect information regarding these maximum premiums. It is shown that if employees' characteristics only differ in the maximum premium they are willing to pay, the employer is unable to perfectly inform himself on these maximum premiums, i.e. he cannot create the right incentives for his employees to reveal their maximum premiums truthfully.

LABOUR‐MARKET ATTACHMENT AND TRAINING PARTICIPATION*

This paper examines how expected attachment to the labour market and expected tenure at a specific firm affect training participation. The results, based on cross‐sectional data from Japan, indicate that expected attachment to the labour market affects participation in both employer‐ and worker‐initiated training, while expected tenure at a specific firm mainly explains participation in employer‐initiated training. These two attachment indices explain more than two‐thirds of the sex gap in training participation. Employers in less‐competitive labour markets are more likely to offer employer‐initiated training to their workers.     

Fair wages survive multiple sources of income inequality

When an employee in a gift exchange game earns significantly less than the employer, the source of employer income does not affect effort choices. However, to induce one unit of effort, the employer has to pay higher wages than in a game without payoff inequality.
