We propose a model for trading in emission allowances in the EU Emission Trading Scheme (ETS). Exploiting an arbitrage relationship we derive the spot prices of carbon allowances given a forward contract whose price is exogenous to the model. The modeling is done under the assumption of no...

One possible explanation for the unsatisfactory implementation of IMF conditionality has been attributed to the lack of credibility of the IMF threat of interrupting financial assistance in case of non compliance with the negotiated conditions. In this paper we suggest that such lack of...

We study the decision of when to invest in an indivisible project whose value is perfectly observable but driven by a parameter that is unknown to the decision maker ex ante. This problem is equivalent to an optimal stopping problem for a bivariate Markov process. Using filtering and martingale...

Online marketplaces for remote labor services allow workers and firms to contract with each other directly. Despite this, a large fraction of the workforce is affiliated with small, autonomous intermediary organizations that are widespread within these markets. This paper shows that...

Online markets for remote labor services allow workers and firms to contract with each other directly. Despite this, intermediaries - called outsourcing agencies - have emerged in these markets. This paper shows that agencies signal to employers that inexperienced workers are high quality....

We show, in an exchange economy with default, liquidity constraints and no aggregate uncertainty, that state prices in a complete markets general equilibrium are a function of the supply of liquidity by the Central Bank. Our model is derived along the lines of Dubey and Geanakoplos (1992). Two...

This paper examines and compares the communication strategies of the Federal Reserve and the European Central Bank, and their effectiveness. First we do a comparative study exercise. We find that on monetary policy committee meeting days both the ECB and the Fed can move market rates using...

Speculative industries exploit novel technologies subject to two risks. First, there is uncertainty about the fundamental value of the innovation: is it strong or fragile? Second, it is difficult to monitor managers, which creates moral hazard. Because of moral hazard, managers earn agency rents...

There is an increasing demand for putting a shadow price on the environment to guide public policy and incentivise private behaviour. In practice, setting that price can be extremely difficult as uncertainties abound. There is often uncertainty not just about individual parameters but about the...
