Research in Economics on COVID-19 posits an economy subject to disease dynamics, which are often seriously misspecified in terms of speed and scale. Using a social planner problem, we show that such misspecifications lead to misguided policy. Erroneously characterizing a relatively slow-moving...

The Arab population in Israel constitutes an ethnic minority, at around 20% of the population. The economy of this minority is characterized by inferior outcomes relative to the Jewish majority by all indicators, including employment, wages, occupational status, social welfare, education, and...

Hiring is a costly activity reflecting firms' investment in their workers. Microdata show that hiring costs involve production disruption. Thus, cyclical fluctuations in the value of output, induced by price frictions, have consequences for the optimal allocation of hiring activities. We outline...

What role does labor play in firms? market value? We explore this question using a production-based asset pricing model with frictions in the adjustment of both capital and labor. We posit that hiring of labor is akin to investment in capital and that the two interact, with the interaction being...

Work of low-skilled migrant workers from developing countries in developed economies is a growing phenomenon and a key political and economic issue. An extensive literature has found (for the most part) that these workers come from the lower part of the skill distribution. This paper revisits...

This paper studies the effects of mass immigration from the former USSR to Israel in the 1990s on the employment of the native-born. The exogeneity and the size of this inflow make it a ?natural experiment? of macroeconomic proportions. An open-economy macroeconomic model is used to analyze this...

The paper explores the consequences of macroeconomic policy for labor market outcomes in the presence of frictions. It shows how policy may be useful in overriding frictions, as well as how it might generate adverse outcomes. The analysis looks at the main tools of macroeconomic policy and...

Does the search and matching model fit aggregate U.S. labor market data? While the model has become an important tool of macroeconomic analysis, recent literature pointed to some significant failures in accounting for the data. This paper aims to answer two questions: (i) Does the model fit the...

This paper studies optimal UI policy from the perspective of worker assignment to heterogenous jobs in an environment of random matching. Workers react to UI policy through job acceptance decisions; firms react to UI policy through wage posting. There is endogenous assortative matching as a...
