We study the effects of a bank’s engagement in trading. Traditional banking is relationship-based: not scalable, long-term oriented, with high implicit capital, and low risk (thanks to the law of large numbers). Trading is transactions-based: scalable, short-term, capital constrained, and with...

This paper investigates empirically the illiquidity of majority blocks of shares in the context of a search model of block trades. The search model incorporates two aspects of illiquidity, or search frictions. First, upon a liquidity shock, the incumbent blockholders may be forced to sell to a...

In this paper we develop a structural model for job search behavior of students entering the labor market. The model includes endogenous search effort and on-the-job search. Since students usually do not start a regular job before graduation but start job search earlier, our model is non...

This discussion paper led to the publication 'Applied Economics' (2009), 41(24), 3093-3101.<P> Assessing the scope for insurance in rural communities usually requires a structural model of household behavior under risk. One of the few empirical applications of such models is the study by Rosenzweig...</p>

In a recent paper Hong and Shum [2006. Using price distributions to estimate search costs. Rand Journal of Economics 37, 257–275] present a structural method to estimate search cost distributions. We extend their approach to the case of oligopoly and present a new maximum likelihood method to...

We present a structural framework for the evaluation of public policies intended to increase job search intensity. Most of the literature defines search intensity as a scalar that influences the arrival rate of job offers; here we treat it as the number of job applications that workers send out....

In this paper we investigate whether markets with heterogeneous network externalities can belocked-in by old technologies even if superior technologies are available. Heterogeneous networkexternalities are present when some consumers care more about the size of the market share of agood than...

We explore the characteristics of a capacity-then-price game for a duopoly market with product differentiation and stochastic demand. The analysis shows that a minimum threshold value for the level of vertical product differentiation exists, relative to horizontal product differentiation, for...
