Regional Shifts in Pork Production: Implications for Competition and Food Safety

U.S. pork production and processing is consolidating in larger, more economically efficient units, and shifting from the Midwest into the Southeast. A regional model of farm supply and processing demand shows that smaller Midwest operations can survive only if processing capacity remains concentrated in that region. Salmonella incidence is higher in the Southeast and on larger farms. Restricting salmonella incidence in hogs delivered for processing to the minimum feasible level would increase total industry costs by 3%, due to increased production and delivery costs. It would also increase the comparative advantage of farms and processing firms in the Midwest.     

Is the European integration speeding up the economic convergence process of the Central and South-Eastern European countries? A shock perspective

In the current context of continuous reassessment of the sustainability of the single currency and gradual enlargement of the euro area during the last decade, the objective of this research is to obtain new insights into the factors that determine the synchronisation of shocks in the Central and South-Eastern European countries vis-à-vis the euro area. The research contributes to the previous work by making a novel use of error correction model in a dynamic panel context which is extended by adding several important omitted variables related to the trade structure and policy coordination. We find that an increase in trade intensity, intra-industry trade and financial integration leads to less frequent asymmetric shocks. On the other hand, divergent fiscal policies are estimated in some model specifications to increase the shock divergence process, although the estimated impact is rather small to counteract the positive effects associated with trade and financial integration. The identified relationships in this research are affected by the significant trade and growth slowdown in the crisis period; while the global economic turmoil has boosted a demand shock convergence, its impact on the supply shocks is in the opposite (diverging) direction.     

Local time and the pricing of time-dependent barrier options

A time-dependent double-barrier option is a derivative security that delivers the terminal value φ(S _T ) at expiry T if neither of the continuous time-dependent barriers b _±:[0,T]→ℝ₊ have been hit during the time interval [0,T]. Using a probabilistic approach, we obtain a decomposition of the barrier option price into the corresponding European option price minus the barrier premium for a wide class of payoff functions φ, barrier functions b _± and linear diffusions (S _t ) _t∈[0,T]. We show that the barrier premium can be expressed as a sum of integrals along the barriers b _± of the option’s deltas Δ _±:[0,T]→ℝ at the barriers and that the pair of functions (Δ ₊,Δ ₋) solves a system of Volterra integral equations of the first kind. We find a semi-analytic solution for this system in the case of constant double barriers and briefly discus a numerical algorithm for the time-dependent case.
