This paper examines the effects of remedial mathematics on performance in university-level economics courses using a natural experiment. We study exam results prior and subsequent to the implementation of a remedial mathematics course that was compulsory for a sub-set of students and unavailable...

The answer is no. Although naive intuition may suggest the opposite, uncertainty about costs in the homogeneous-good Bertrand model intensifies competition: it lowers price and raises total surplus (but also makes profits go up). For some economic environments, this is implied by Hansen’s...

We study a monopoly insurance model with endogenous information acquisition. Through a continuous effort choice, consumers can determine the precision of a privately observed signal that is informative about their accident risk. The equilibrium effort is, depending on parameter values, either...

A uniform pricing rule may enable the communication of demand information from buyer to seller in situations where this would not have been possible if the seller could price discriminate. Importantly, such a rule can benefit both buyer and seller.

This paper studies the falsifiability of the hypothesis of Nash behavior, for the case of a finite number of players who choose from continuous domains, subject to constraints. The results obtained here are negative. Assuming the observation of finite data sets, and using weak, but nontrivial,...

Policy makers make policy decisions, which affect the utility of private citizens. The traditional explanation for government intervention in the economy is the existence of market failure. Nevertheless, despite public policy interventions, the economy may fail to reach the efficient frontier....

Restrictions preventing regulators from setting standards on a firm by firm basis are commonly assumed to be inefficient. Existing rationales for their prevalence have been politico-economic. We provide an efficiency interpretation. We characterise settings in which the requirement that firms be...

Minimum standards set by a ‘World Environmental Organisation’ (WEO) and NGO labelling are promoted as alternative approaches to international environmental protection. We explore the potential inter-play between these two approaches when the WEO is subject to pressure from producers. We find...

Voting theory has always focused on mechanism design, but this paper shows that voting theory is also a useful tool in the field of preference representation. Both the lexicographic order on n-dimensional Euclidean space and the threshold of detectable difference relation are pairwise majority...

We model growth in dictatorships facing each period an endogenous probaibility of "political catastrophe" that would extinguish the regime's wealth ability. Domestic capital exhibits a bifurcation point determining economic growth or shrinkage. With low initial domestic capital the dictator...
