Person-to-person transmission in the workplace is thought to play a crucial role in the spread of COVID-19. Labor unions are among the largest institutions in the United States, and their role in regulating employee-employer relations is hard to ignore. Costly efforts to contain the virus...

I investigate the ethics of money production, consider theories of ethics which can cover my discussion and then I will have a look on the history of money production. Last part has been dedicated to adjust these two different fields and as conclusion, I found that: by definition in which we...

Urban sprawl contributes to the heat island effect by eliminating vegetation, expanding dark surfaces, and increasing daily travel distance. This study quantifies this effect by constructing and linking the required measures and exploiting variations in the data using different identification...

Several recent papers argue that contracts provide reference points that affect ex post behavior. We test this hypothesis in a canonical buyer-seller relationship with renegotiation. Our paper provides causal experimental evidence that an initial contract has a highly significant and...

We present an international trade model with multiproduct firms. Firms are heterogeneously endowed with two types of capabilities that jointly determine the trade-off within firms between managing a large portfolio of products and producing at low marginal cost. The model can explain many of the...

This paper reports data from a laboratory experiment on two-period moral hazard problems. The findings corroborate the contract-theoretic insight that even though the periods are technologically unrelated, due to incentive considerations principals can benefit from offering long-term contracts...

We study a continuous-time game of strategic experimentation in which the players try to assess the failure rate of some new equipment or technology. Breakdowns occur at the jump times of a Poisson process whose unknown intensity is either high or low. In marked contrast to existing models, we...

We study endogenous group formation in tournaments employing experimental three-player contests. We find that players in endogenously formed alliances cope better with the moral hazard problem in groups than players who are forced into an alliance. Also, players who are committed to expending...

The compensation of executive board members in Germany has become a highly controversial topic since Vodafone's hostile takeover of Mannesmann in 2000 and it is again in the spotlight since the outbreak of the financial crisis of 2009. Based on unique panel data evidence of the 500 largest firms...
