Understanding ICC Rate Structure Regulation: A Spatial Analysis

A spatial equilibrium of a stylized railroad network is offered to illustrate that monopoly pricing requires prices on some links that are so high that traffic “does not move.” ICC price structure regulation, which was based on the idea that traffic should be priced to “move” in a privately owned and operated network, is modeled as maximizing market access subject to an AVC minimum and an aggregate break-even constraint in a network that is over-extended. Flows that result from such regulation are highly inefficient but provide more surplus to shippers and receivers than the unregulated price structure.     

Is local bias a cross-border phenomenon? Evidence from individual investors’ international asset allocation

Extant literature consistently documents that investors tilt their domestic equity portfolios towards regionally close stocks (local bias). We hypothesize that individual investors’ local bias is not limited to the domestic sphere but instead also determines their international investment decisions. Our results confirm the presence of a cross-border local bias. Specifically, we show (i) that the stockholdings of individual investors living within regional proximity to a foreign country display a significantly lower foreign investment bias towards investment opportunities in that country and (ii) that this drop in foreign investment bias levels is disproportionately driven by investments in regionally close neighbor-country companies. The impact of cross-border local bias on investors’ bilateral foreign equity investments is economically significant and holds even after controlling for previously identified explanations of international asset allocation.
