Using Lasso-Type Penalties to Model Time-Varying Covariate Effects in Panel Data Regressions: A Novel Approach Illustrated by the "Death of Distance" in International Trade
Hess, Wolfgang; Persson, Maria; Rubenbauer, Stephanie; … - 2013
When analyzing panel data using regression models, it is often reasonable to allow for time-varying covariate effects. We propose a novel approach to modelling timevarying coefficients in panel data regressions, which is based on penalized regression techniques. To illustrate the usefulness of...

The Death of Distance Revisited: Cyberplace, Physical and Relational Proximities
Tranos, Emmanouil; Nijkamp, Peter - 2012
This paper studies the impact of physical distance and different relational proximity types on the formation of the Internet infrastructure. Although there is some anecdotal evidence on the 'end of geography' effect of the Internet, the relationship between physical space and the Internet has...

Putting Quantitative Models to the Test: An Application to Trump's Trade War
Adão, Rodrigo; Costinot, Arnaud; Donaldson, Dave - 2023
The primary motivation behind quantitative modeling in international trade and many other fields is to shed light on the economic consequences of policy changes. To help assess and potentially strengthen the credibility of such quantitative predictions we introduce an IV-based goodness-of-fit...

Assessing general and partial equilibrium simulations of Doha round outcomes using meta-analysis
Hess, Sebastian; von Cramon-Taubadel, Stephan - 2007
Applied general and partial equilibrium models are widely used tools for ex ante analysis of trade policy changes. However, simulation results seem to exhibit significant variation across publications, and the often criticised ‘black box’ character of applied trade models makes meaningful...

Trade policy and export diversification: What should Colombia expect from the FTA with the United States
Volpe Martincus, Christian; Gómez, Sandra Milena - 2009
Sectoral concentration of exports has been a longstanding matter of concern for policymakers in developing countries. According to the economic theory and recent empirical evidence, improved market access through trade arrangements is likely to favor export diversification. In this paper, we...

On estimation of gravity equation: A cluster analysis
Bobková, Božena - 2014
This article questions the slope homogeneity in a gravity equation and proposes a partially heterogeneous framework for … its estimation using panel data. We suggest to employ K-mean clustering to group countries according to the gravity … equation variables. Further, the gravity model is estimated on these created homogeneous groups. We apply this procedure on …

Gravity model analysis: Robust evidence from the Czech Republic and corruption matching
Paulus, Michal; Michalíková, Eva - 2014
The results generally confirm that Czech trade is oriented towards European countries and determined primarily by key economic factors of domestic and foreign GDP. The institutional variables remain largely insignificant, except corruption due tothe counterintuitive result that a higher...

Air accessibility and the export of Italian manufacture in Europe: Evidence at regional level
Alderighi, Marco - 2013
We study the link between air accessibility (measured by non-stop flights offer) and the manufacturing export of the Italian regions in Europe using a panel of 12,000 half-yearly observations ranging from 1998 to 2010. The analysis shows that the supply of non-stop flights provided by...

Aid and Trade - A Donor's Perspective
Nowak-Lehmann D., Felicitas Nowak-Lehmann; Martínez … - 2009
One reason donors provide foreign aid is to support their exports to aid-recipient countries. Time series data for Germany suggests an average return of between US$ 1.04 to US$ 1.50 for each US dollar of aid spent by Germany. Although this is well below previous estimates, the value is robust to...
