There is a fundamental difference between the natural and the social sciences due to reactivity. This difference remains even in the age of Artificially Intelligent Learning Machines and Big Data. Many academic economists take it as a matter of course that economics should become a natural...

This paper introduces harassment in a model of bribery and corruption. We characterize the harassment equilibrium and show that taxpayers with all possible levels of income participate in such an equilibrium. Harassment has a regressive bias. Harassment cost as such may not affect tax revenue....

This paper examines how skill-biased growth can generate economic fragmentation (income disparities) that give rise to social fragmentation (the adoption of increasingly incompatible social identities and values), which generate political fragmentation (the adoption of increasingly incompatible...

This paper develops a small open economy (SOE) dynamic stochastic general equilibrium (DSGE) model that helps to explain business cycle synchronization between an emerging market and advanced economies. The model captures the specificities of both economies (e.g. primary commodity,...

This paper proposes a simple partial equilibrium model to investigate the effects of government policy on venture capital backed investments. Giving up an alternative career, entrepreneurs focus their effort on a single, high risk venture each. Venture capitalists acquire an equity stake and...

Robust decision making implies welfare costs or robustness premia when the approximating model is the true data generating process. To examine the importance of these premia at the aggregate level we employ a simple two-sector dynamic general equilibrium model with human capital and introduce an...

This paper proposes and analyses a model of start-up investment. Innovative entrepreneurs are commercially inexperienced and can benefit from venture capital support. Only part of them succeed in matching with a venture capitalist while the rest must resort to standard bank finance. We consider...

A great deal of late bidding has been observed on internet auctions such as eBay, which employ a second price auction with a fixed deadline. Much less late bidding has been observed on internet auctions such as those run by Amazon, which employ similar auction rules, but use an ending rule that...
