A Habit-Based Explanation of the Exchange Rate Risk PremiumNo 872, 2006 Meeting Papers from Society for Economic Dynamics Abstract: This paper presents a fully rational general equilibrium model that produces a time-varying exchange rate risk premium and solves the uncovered interest rate parity (U.I.P) puzzle. In this two-country model, agents are characterized by slow-moving external habit preferences similar to Campbell & Cochrane (1999). Endowment shocks are i.i.d and real risk-free rates are time-varying. Agents can trade across countries, but when a unit is shipped, only a fraction of the good arrives to the foreign shore. The model gives a rationale for the U.I.P puzzle: the domestic investor receives a positive exchange rate risk premium when she is effectively more risk-averse than her foreign counterpart. Times of high risk-aversion correspond to low interest rates. Thus, the domestic investor receives a positive risk premium when interest rates are lower at home than abroad. The model is both simulated and estimated. The simulation recovers the usual negative coefficient between exchange rate variations and interest rate differentials. When the iceberg-like trade cost is taken into account, the exchange rate variance produced is in line with its empirical counterpart. A nonlinear estimation of the model using consumption data leads to reasonable parameters when pricing the foreign excess returns of an American investor Keywords: Exchange rate; Time-varying risk premium; Habits (search for similar items in EconPapers) Downloads: (external link) Related works: Access Statistics for this paper More papers in 2006 Meeting Papers from Society for Economic Dynamics |
