ABSTRACTThis paper estimates outflow equations for the unemployed and job vacancies under random and stock–flow matching using Japanese data. We find that for the outflow of the unemployed, the stock–flow matching model fits better than the random matching model at the quarterly frequency, but not at the monthly frequency. In contrast, the outflow of vacancies is affected by the stock of the unemployed as well as its inflow at both monthly and quarterly frequencies. In addition, we calculate the exit rates of the unemployed and job vacancies to show the relationship between the exit rates and the durations of unemployment and job vacancies.

ABSTRACTThis paper studies firms' job creation decisions in a labour market with search frictions. A simple labour market search model is developed in which a firm can search for a second employee while producing with a first worker, and this creates the equilibrium size distribution of firms. A firm expands employment even if the instantaneous payoff to a large firm is less than that of staying small – a firm has a precautionary motive to expand its size. In addition, this motive is enhanced by a greater market tightness. Because of this effect, firms' decisions become interdependent – a firm creates a vacancy if it expects other firms to do the same, creating strategic complementarity among firms and thereby self‐fulfilling multiple equilibria. An increase in productivity can cause a qualitative change in labour market tightness and the rate of unemployment.

Research in the field of customer discrimination has received relatively little attention even if the theory of discrimination suggests that customer discrimination may exist in the long run whereas employer and employee discrimination may not. This paper examines customer discrimination considering a unique dataset from the most popular sports industry in India, i.e., cricket. Relying on Playing XI vote in the Indian Premier League (IPL), we analyze whether supporters have a different personal preference towards players based on their location of origin and religion. In contrast to the often-heated rhetoric surrounding discrimination, the often-unfounded assertions surrounding diversity, and the previous literature, we overall do not find any discrimination in voting. Our overall findings suggest that supporters treat players equally irrespective of nationality, place of origin or religious background while selecting their favorite players. However, our results also suggest that examining discrimination by controlling for proxy productivity characteristics may produce bias results as certain included or excluded characteristics may be systematically different. Our findings further suggest that political conflict may lead to customer discrimination. And finally, in line with Heckman's (1998) argument, our results suggest that customer discrimination may exist on the margin.
