A Regime Switching Analysis of Exchange Rate Pass-Through

Kólver Hernández and Aslı Leblebicioğlu

ABSTRACT

We investigate changes in the pricing policies of exporters, including changes in the exchange rate pass-through elasticity, and changes in the elasticities of variables that affect the firm’s markup. We set up a theoretical model of optimal export pricing in order to illustrate how changes in the pass-through elasticity can emerge together with changes in other elasticities in the pricing policy. Based on our theoretical formulation, we empirically study changes in all the elasticities that define the pricing policy as opposed to focusing only on the exchange rate pass-through. In the empirical model, we assume that in every period exporters get to set prices by following either a “high pass-through” or a “low pass-through” pricing policy. The transition from one policy to the other is governed by a Markov process whose transition probabilities depend on economic fundamentals. We estimate the model using data we have collected on 35 lines of imported cars to the US, from seven exporting countries, for the 1980-2004 period. We find that the “low pass-through” regime is characterized by: a low exchange rate pass-through; a low response to misalignments in the firm’s relative price; a low volatility of technology and preference shocks; and a higher duration than the high pass-through regime. Monetary stability and the market structure are significant factors behind the switching of pricing policies. Ceteris paribus, monetary stability measured as the cross-country inflation differential explains abut 22% of the year-to-year variation in the exchange rate pass-through coefficient; when measured by the volatility of the exchange rate, it explains 37%. Market concentration measured by the Herfindahl index explains about 40%.

The Lerner College is home to a state-of-the-art financial trading facility, the $1.5 million student-led Blue Hen Investment Club, a student-managed restaurant and hotel, a high-technology development center of a global bank and a start-up experience for students with new business ideas.

Lerner College faculty - like Meryl Gardner, whose research on foods and moods was recently published in the Journal of Consumer Psychology - are thought leaders who command attention from influential business audiences, economists and policy makers.

All Lerner College departments offer discovery learning experiences and emphasize data-based analytics to enrich the student experience. Here, students at Vita Nova, our award-winning restaurant run through HRIM, joined professional chefs and winemakers in hosting a 2014 Mid-Atlantic Wine and Food Festival event.

The Institute for Financial Services Analytics is a collaboration between the Lerner College, UD's College of Engineering and JPMorgan Chase, and hosts events for academics and the business community designed to address consumer analytics and industry applications.

Undergraduate scholarships, made possible through the generosity of alumni and friends, enable us to support promising scholars. Here, Delaware Gov. Jack Markell and his mother, Leni Markell, join recipients of the William Markell Scholarship (center), which benefits students in Accounting and MIS.
