KAZAKOVA Ekaterina (Mannheim) : Export Platforms and Multinational Demand Risk Diversification


This paper analyzes the effects of correlated aggregate demand shocks on multinational firms’ structure. Accordingly, we build a structural model featuring global production and demand risk in which heterogeneously risk averse managers decide on the location of production plants, the set of countries to serve from these plants, and the volume of sales. These decisions hinge on the expected market demand, and the variance-covariance of the demand shocks in destination markets. The identification of firm-specific risk aversion coefficients follows from existence and uniqueness of the firm’s optimal sales portfolio. The empirical analysis uses firm-level data on German multinational companies. Our results support the existence of MNE’s diversification strategies when producing and selling abroad.

RIVERA Thomas (HEC) : Robust Mechanisms for the Regulation of Bank Risk

This paper aims at designing mechanisms for the regulation of bank risk (probability of default) that can guarantee robustness to large misspecifications of the regulators information regarding the bank’s assets. Assuming banks can (on average) discern the true level of risk of the other regulated banks, I construct a robust mechanism that allows the regulator to bound the worst case probability of bank failure by any arbitrary amount. In doing so, I show that any informationally robust mechanism must necessarily require banks to issue subordinated debt to other regulated banks and must provide a way to guarantee a minimal probability of joint bank failure between at least two of the banks. We show how the regulator can achieve the latter objective by providing a single bank with an explicit guarantee against losses in the event that another bank fails and how, when coupled with a minimum subordinated debt requirement and interest rate ceiling, such a guarantee can ensure an arbitrarily low probability of any regulated bank’s failure. Finally, I discuss how the results are affected when banks have biased estimations of other banks’ risks and the best bound on bank risk that the regulator can achieve given such biases.

AVRAM Silvia (ISER, U. Essex) : The role of taxes and benefits in smoothing income shocks

We examine the extent to which the tax benefit system in the UK smooths income shocks across the life cycle between 1991 and 2008. Using the BHPS, we first estimate six different income concepts ranging from individual gross earnings to net household (equivalised) disposable income. For each income concept, we then decompose its variance into three components-heterogeneous growth, permanent shocks and transitory shocks. We then quantify the extent to which variance in income due to heterogeneity, permanent and transitory shocks is affected by four types of policy instruments, namely taxes, contributory benefits, means-tested benefits and other (mainly disability) benefits. Preliminary results show that the UK tax benefit does play an important role in reducing income variance, especially the portions attributable to heterogeneity and to a (lesser extent) permanent shocks. Contributory benefits have the strongest effects, more than halving the variance attributable to heterogeneity and permanent shocks ; other benefits and means-tested benefits also reduce considerably the variance due heterogeneity but appear to have a minimal effect on the variance of shocks, either permanent or transitory. Taxes play no role in the reduction of income variance.

HANDBURY Jessie (Wharton - University of Pennsylvania) : Is the focus on food deserts fruitless ? Retail access and food purchases across the socioeconomic spectrum

Using comprehensive data describing the healthfulness of household food purchases and the retail landscapes consumers face, we ask whether spatial differences in access are to blame for socioeconomic disparities in nutritional consumption. We find that differences in access, though significant, are small relative to differences in the nutritional content of sales. Household consumption responds minimally to improvements in local retail environments in the short run, and socioeconomic disparities persist among households with equivalent access. Our results indicate that even in the long run, access-improving policies alone can eliminate at most one fifth of existing disparities in nutritional consumption.
