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 $1.4 million student-led Blue Hen Investment Fund, 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 Anu Sivaraman, who is among Social Media Marketing Magazine’s “Top 100 Marketing Professors on Twitter” and’s “Top 50 Marketing Professors on Twitter” - are thought leaders who command attention from influential business audiences, economists and policy makers.

All Lerner College departments offer experience-driven learning and emphasize evidence-based analytics methods to enrich the student experience. Here, finance students visit New York City’s financial districts for a first-hand look at markets trading and to meet with UD alumni.

Charles W. Horn, AS75, and wife Patricia, recently made a $3 million commitment to enhance and expand entrepreneurial studies.
