This paper shows the importance of correcting for sample selection when investing in illiquid assets with endogenous trading. Using a large sample of 20,538 paintings that were sold repeatedly at auction between 1972 and 2010, we find that paintings with higher price appreciation are more likely...

We analyze a market where firms compete in a conventional and an electronicretail channel. Consumers easily compare prices online, but some incur purchaseuncertainties on the online channel. We investigate the market shares of the two retailchannels and the prices that are charged. We find that...

We analyze the incentives for incumbent bricks-and-mortar firms and newentrants to start an online retail channel in a differentiated goods market. Tothis end we set up a two-stage model where firms first decide whether or notto build the infrastructure necessary to start an online retail...

This paper develops a model for multi-store competition between firms. Using thefact that different firms have different outlets and produce horizontally differentiated goods, we obtain a pure strategy equilibrium where firms choose a different location for each outlet and firms' locations are...

Transaction costs are a major reason why international trade flows are much smaller than traditional trade theory would suggest. Trust between trading partners lowers transaction costs and may therefore enhance trade. The empirical analysis of this paper shows that more trust leads to more trade...

Economists increasingly pay attention to social capital as an important determinant of macroeconomic growth performance. At the same time, there is discussion regarding the robustness of the results of empirical growth studies. In a seminal paper, Knack and Keefer (1997) assess the effect of...

There is increasing empirical and experimental evidence thatproviding financial incentives to agents to performcertain socially desirable actions may permanently reduce other typesof motivations to undertake these actions.We study the impact of financial incentives on the desire for...

In this paper we test the celebrated `Strength of weak ties' theory of Granovetter (1973). We test two hypotheses on the network structure in a data set of collaborating economists. While we find support for the hypothesis of transitivity of strong ties, we reject the hypothesis that weak ties...

Impact evaluations of development programmes usually focus on a comparison of participants with a control group. However, if the programme generates externalities for non-participants such an approach will capture only part of the programme’s impact. Based on a unique large-scale quantitative...

This paper reviews three distinct strategies in recent economics for using the concept of social identity in the explanation of individual behavior: Akerlof and Kranton’s neoclassical approach, Sen’s commitment approach, and Kirman et al.’s complexity approach. The primary focus is the...
