| CGE models are widely used tools for economic assessments of trade policy changes. However, overall confidence in their results tends to be low. We employ the methodological framework of meta-analysis in order to approach a quantitative comparison of CGE-based simulation results. Therefore, we compile a dataset of twelve recent Doha simulations and fit a linear regression model that explains the variance between simulation results on the regional level as a function of various modeling characteristics. The estimates are broadly in range with documented qualitative knowledge about modeling assumptions. The size of the sample limits general conclusions; however, an ongoing research project will extend the approach to a larger sample. |

| Over the time a large number of reciprocal preferential trade agreements (RTAs) have been concluded among countries. Recently many studies have used gravity equations in order to estimate the effect of RTAs on trade flows between partners. These studies report very different estimates since they differ greatly in data sets, sample sizes and independent variables used in the analysis. So, what is the "true" impact of RTAs? This paper combines, explains and summarizes a large number of results (1827 estimates included in 85 papers), using a meta-analysis (MA) approach. Notwithstanding quite a high variability, studies consistently find a positive RTAs impact on bilateral trade: the hypothesis that there is no effect of trade agreements on trade is easily and... |

| International cereal prices (in US dollar terms) have been increasing since 2003, but it is domestic prices that affect food consumption and production. This paper analyzes, for seven large Asian countries, the extent to which domestic prices have increased since 2003 and presents several conclusions. First, the data show that the increases in world cereal prices have been accompanied by a real depreciation of the US dollar. For many countries (but not all), this depreciation has neutralized a substantial proportion of the increase in world prices. Second, domestic commodity specific policies in several of these Asian countries have further stabilized domestic prices relative to the change in world prices. This has been especially true for rice, the main... |

| This paper revisits the empirical evidence about the link between firms’ performance and their international status, based on a large sample of Italian enterprises. To this purpose, we merged two waves of the Capitalia survey (1998-2000, and 2001-2003) retrieving firm level data for roughly 7,000 units. Three results stand out from our empirical exercise. First, firms that engage in the foreign production of final goods, in addition to export activities, are more productive than firms that only export abroad. Second, firms that engage in final goods off-shoring are more productive than firms that engage in inputs off-shoring. Third, in terms of the productivity dynamics over the period 1998-2003, exporters’ performance in Italy was not any better than the... |

| Quantification of welfare changes due to trade liberalisation play a crucial role for political decision making. However, meaningful comparisons of simulation results from different sources are difficult. Often significant differences in simulated gains from liberalisation do not serve to increase confidence in quantitative assessments based on trade models. We employ a metaanalysis of applied trade simulations under the WTO Doha Round to identify model characteristics that influence the magnitude of simulation results, and to estimate the magnitude of this influence. Findings from our simple econometric model are plausible and show that each simulation experiment represents a complex interaction of experimental settings that may not easily be understood... |

| The paper is inviting a reader to think to what extent we can use the knowledge resulting from laws of nature for exploring economic processes. In order to look for the answers on this question, the paper is going to explore international trade flows between the Baltic Sea region countries using a gravity approach. Attention is paid to analyzing forces that attract foreign trade flows and to exploring the influence of distance as an indicator that expresses both transportation costs and cultural proximity of the countries. The results of modeling support the statement that the size of economy has statistically significant and positive influence on the bilateral trade relations of the region. The influence of economic development level that is expressed by... |
