International climate negotiations have been troubled by mutual mistrust. At the same time, a hope seems to prevail that once enough countries moved forward, others would follow suit. If the abatement game faced by climate negotiators is a Prisoners' Dilemma, and countries are narrowly...

Many people remain opposed to climate change mitigation policies. This opposition is an obstacle to policy action and, therefore, important to understand. We explore how unusually high temperatures (heat waves), which observably increase the salience of climate change-related issues, affect...

Conventional wisdom depicts corruption as a tax on incumbent firms. This paper challenges this view in two ways. First, by arguing that corruption matters not so much because of the value of the bribe ("tax"), but because of another less studied feature of corruption, namely bribe...

This paper studies the influence of information on entry choices in a competition with a controlled laboratory experiment. We investigate whether information provision attracts mainly high productivity individuals and reduces competition failure, where competition failure occurs when a subject...

Entrepreneurs who decide to enter an industry are faced with different levels of effective entry costs in different countries. These costs are heavily influenced by economic policy. What is not well understood is how international trade affects the government incentive to impact on entry costs,...

We model entry by entrepreneurs into new markets in developing economies with regulatory barriers in the form of licence fees and bureaucratic delay. Because laissez faire leads to quot;excessivequot; entry, a licence fee can increase welfare by discouraging entry. However, in the presence of a...

This paper studies aggregate dynamics in a cobweb model where learning takes place through a selection mechanism, by which more successful firms are replicated at a higher rate. The structure of the model allows to characterize analytically the aggregate dynamics, and to compute the effect on...

We investigate whether excessively optimistic beliefs may play a role in the persistent demand for doctoral and post-doctoral training in science. We elicit the beliefs and career preferences of doctoral students through a novel survey and randomize the provision of structured information on the...

This paper identifies several distortions which create barriers to entrepreneurship. First, in addition to the innate entry cost, there are entry costs caused by regulation. Second, union wage policies raise the opportunity cost of entrepreneurship. Third, inefficiencies in the transmission of...

We develop a theoretical and empirical analysis of the impact of barriers to entry on workplace training. Our theoretical model yields ambiguous predictions on the sign of this relationship. On the one hand, given the number of firms, a deregulation reduces profits per unit of output, and...
