I use the automated search algorithm to address practical issues that arise in estimating income and price elasticities for U.S. trade in services: specification of dynamics, specification of the search strategy, simultaneity biases, and aggregation biases. Specifically, starting from a general,...

Non-linear modeling approaches, including Smooth Transition Autoregressive (STAR) models, have attracted a great deal of attention over the last two decades. The empirical application of these models, however, is not always a straightforward task. In particular, parameter estimation and...

The paper revisits dynamic term structure models (DTSMs) and proposes a new way in dealing with the limitation of the classical affine models. In particular, this paper expands the flexibility of the DTSMs by applying a fractional Brownian motion as the governing force of the state variable...
