Communication with Endogenous Deception Costs
écrit avec Ran Eilat (BGU)
We study how the suspicion that communicated information might be deceptive affects the nature of what can be communicated in a sender-receiver game. Sender is said to emph{deceive} Receiver if she sends a message that induces beliefs that are different from those that should have been induced in the realized state. Deception is costly to Sender and the cost is endogenous: it is increasing in the distance between the induced beliefs and the beliefs that should have been induced. A message function that induces Sender to engage in deception is said to be non-credible and cannot be part of an equilibrium. We study credible communication in the frameworks of cite{crawford_sobel_1982} and cite{kamenica_bayesian_2011}. The cost of deception parametrizes the sender's ability to commit to her strategy. Through varying this cost, our model spans the range from cheap talk, or no commitment, to full commitment

Intra- vs. international transport costs -- the case of US exports to Canada and Mexico
Trade economists have intensively investigated the impact of international trade costs on trade flows by using distance measures as a robust approximation of trade costs. However, traditional distance measures between trading partners usually are too aggregated across space to separately inform about the effect of intra-national and international transport costs on trade flows. This paper draws on detailed transport-data for the US to analyse the effect of intra-national transport costs on exports based on a structural gravity model estimated by a Poisson Pseudo-Maximum Likelihood. The results reveal that intra-national transport costs of US exports are lower in absolute terms than their international counterparts: An increase in intra-US distance by 1% is associated with a decrease in US exports by on average .5% compared to 1.2% for international transport distance. Further results on distances travelled by different transport modes imply that trade impediments related to road transportation have a significantly stronger effect on US-exports than those related to other major transport modes studied in this paper. These findings are of interest to policy-makers and academics alike: to support policy-decisions about national infrastructure projects related to international integration and sustainable development, as well as to exploit a more precise measure of intra-national trade costs for structural gravity analysis.

Climate Change, Directed Innovation and Energy Transition: The Long-run Consequences of the Shale Gas Revolution
We look at the short and long term effects of a shale gas boom in an economy where energy can be produced with coal, or shale gas, or a clean energy source. In the short run, a shale gas revolution has counteracting effects on CO2 emissions: on the one hand it allows countries to substitute away from coal which in turn reduces CO2 emissions everything else equal; on the other hand the shale gas boom may increase pollution as it increases the scale of aggregate production. In the long run a shale gas boom tends to increase CO2 emissions as it induces Örms to direct innovation away from clean innovation towards shale gas innovation, and we show the possibility of an infinitely delayed switch from shale gas to clean energy. We then derive conditions on the parameters under which, as a result of the above trade-off, the shale gas revolution reduces emissions in the short-run but increases emissions in the long-run. We then use data on electricity production to calibrate the model.
