State-Dependent Nominal Rigidities & Disinflation Programs in Small Open Economies

Kólver Hernández


    Experiences of high-inflation economies suggest that exchange rate-based (ERB) and money-based (MB) disinflations induce sharply different dynamics in consumption and GDP. I study the role of nominal rigidities to explain such dynamics. I build on Calvo pricing to introduce elements of state-dependent into an otherwise standard small open economy. This new feature delivers state-dependent nominal rigidities (SDNR). Nonlinear simulations show that the model with SDNR generates a dynamic behavior consistent with both ERB and MB disinflations; however the model’s special case with constant nominal rigidities is not successful rationalizing ERB disinflations.

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.

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.

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.

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.

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.
