This paper proposes a test for the existence and the degree of contagious presenteeism and negative externalities in sickness insurance schemes. First, we theoretically decompose moral hazard into shirking and contagious presenteeism behavior. Then we derive testable conditions for reduced...

For a risk neutral lender and a group of borrowers facing identical revenue risks we compare individual loans and group lending. We stress the importance of group liquidity in defining the necessary risk premium. There are no welfare differences between the loan forms. However, the default rates...

We examine an auction model where there are many different goods, each good has multiple units, and bidders have gross substitutes valuations over the goods. We analyze the number of iterations in iterative auction algorithms for the model based on the theory of discrete convex analysis. By...

The paper empirically assesses microeconomic exporting-productivity nexus using the data for Ukrainian manufacturing and service sectors for the years 2000-2005. The results of the estimation show that firms with higher total factor productivity (TFP) levels in the period prior to entry are much...

This paper reports an experiment designed to elicit social preferences over income compensation schemes, where income differences between subjects have two independent components: one due to chosen effort and the other due to random chance. These differences can be compensated through social...

Ageing populations place an increasing financial burden on governments. Retired older workers are a source of untapped economic capacity. Maestas (2010) finds 26% of Health and Retirement Study (HRS) sample respondent’s ‘unretire’. We estimate unretirement rates between 5.5...

This paper analyses the temporary unemployment regulations that several governments of European countries have introduced during the recent recession. We view these measures as a collection of real options that governments provide to firms and value these options. We study, in particular, the...
