Following the gains from variety literature, this paper estimates the welfare impact of growth of the variety of imported goods in 28 countries in East Africa and East Asia and compares the results. While estimating the gains from variety, the elasticities of substitution are estimated for each...

We provide a selective overview of the literature on the linkages between interstate conflict and international trade, paying special attention to how trade openness (i) affects arming incentives, (ii) the channels through which its effects travel, and (iii) its consequences for the emergence of...

We study the aggregate implications of production network formation in a quantitative multi-location general equilibrium trade model. Firms search for suppliers and buyers across locations subject to matching frictions, generating a gravity structure of production networks. We develop sufficient...

Im Gefolge der Preisrückgänge für importierte Rohstoffe hat Deutschland im vergangenen Jahr erhebliche Realeinkommensgewinne eingefahren. Vom preisbereinigten Bruttoinlandsprodukt (BIP), das zeitgleich leicht gesunken ist, wird dieser Kaufkraftzuwachs nicht abgebildet. Einen umfassenderen...

We study the role of firm heterogeneity and imperfect competition for global production networks and the gains from trade. We develop a quantifiable trade model with two-sided firm heterogeneity, matching frictions, and oligopolistic competition upstream. More productive buyers endogenously...

We show that climate policy can unlock large environmental gains from trade by inducing economies to specialize according to their environmental comparative advantage. We make this point by exploring the effects of a carbon tax in a quantitative trade model. Our main result is that the...

A central argument for trade liberalization is that when the 'gains from trade' are shared, countries see large gains in economic development. In this paper, I empirically evaluate this argument and assess the impact of elite capture on regional development. Africa provides a unique study ground...

We use Belgian data on domestic firm-to-firm transactions and ask how the measurement of the share of imports in final consumption is affected when one uses data recorded at higher levels of aggregation. We find that aggregating detailed firm-to-firm transaction data to the firm level and...

Das preisbereinigte Bruttoinlandsprodukt als zentrales Maß für die im Inland erwirtschafte Leistung hat im Jahr 2022 die heimische Wohlfahrtsentwicklung überschätzt. Denn im Gefolge der Verschlechterung der Terms of Trade ist ein Teil des in Deutschland erwirtschafteten Realeinkom- mens ins...

We develop a structural framework to identify the sources of cross-state heterogeneity in response to US tariff changes. We quantify the effects of unilaterally increasing US tariffs by 25 percentage points across sectors. Welfare changes range from −0.8 percent in Oregon to 2.1 percent in...

We develop a general equilibrium structural model with heterogeneous workers and nonhomothetic preferences to quantify the unequal individual-level gains from trade liberalization. The results show that in developed countries, the distribution of gain from trade is relatively balanced. However,...

Power laws in productivity and firm size are well documented empirical regularities. As they are upper right-tail phenomena, this paper shows that assuming asymptotic power functions for various model primitives (such as demand and firm heterogeneity) are sufficient for matching these...

Border procedures around the globe can act as barriers hindering international trade. Another impact of these procedures relates to their economic resource costs. In this study, using a microeconomic framework of international trade, the potential economic gains are estimated for reductions in...

For a large class of structural gravity models in the literature, the gains from trade of a country increase with trade openness based on a common trade elasticity across countries. This paper shows that when the trade elasticity is allowed to be country specific and it increases with trade...

We use Belgian data on domestic firm-to-firm transactions and ask how the measurement of the share of imports in final consumption is affected when one uses data recorded at higher levels of aggregation. We find that aggregating detailed firm-to-firm transaction data to the firm level and...

We investigate how trade shocks affect the allocation of labor across plants at the local labor market level. Using Brazil's import liberalization as a quasi-natural experiment, we uncover a new margin for the gains from trade: the reallocation of labor from smaller to larger producers in the...

This paper introduces endogenous workplace quality choice into an international trade model with a monopsonistically competitive labour market, in which firms compete for potential employees by offering them a combination of monetary and non-monetary benefits. To attract the workers required to...

In this paper, I empirically evaluate this argument and assess the impact of elite capture on regional development. Africa provides a unique study ground...

We measure gains from trade in multi-sector economies with non-homothetic preferences where changes in trade costs generate reallocation of expenditure across sectors. We show how to measure the trade elasticity and how it relates to welfare. In this environment, the trade elasticity now varies...

We study welfare gains from trade in a dynamic, multicountry model with capital accumulation. We compute the exact transition paths for 93 countries following a permanent, uniform, unanticipated trade liberalization. We find that while the dynamic gains are different across countries,...

Solving a workhorse incomplete markets model in continuous time is many times faster compared to its discrete time counterpart. This paper dissects the computational discrepancies and identifies the key bottlenecks. The implicit finite difference method – a commonly used tool in continuous...

With the occurrence of overweight and obesity strongly linked to the onset of three of the four most common causes of death and morbidity (cardiovascular disease, diabetes, and cancer), the financial impacts of individuals’ excess weight on public health systems is translating into societal...

This paper examines the extent to which gains-from-trade predictions from commonly-used trade theories are consistent with observed household consumption decisions. Our approach is based on inference from household-level estimation of food Engel curves in the US and in a few other countries. For...

How large are the welfare gains from trade? Would such gains be significantly amplified in the long run when productivity is endogenously enhanced? To address these questions, we focus on the dynamic effect of trade, in particular, how trade affects the incentives for technological advancement....

In the wake of the U.S.-Canada Free Trade Agreement, both the U.S. and Canada experienced a sustained increase in job reallocation, including firms moving into exporting. The change involved big firms as much as small firms. To mimic these patterns,we formulate a model of innovation by both...

Das Statistische Bundesamt veröffentlicht neben dem preisbereinigten Bruttoinlandsprodukt auch den Realwert des Bruttoinlandsprodukts. Die beiden Indikatoren unterscheiden sich um den Terms-of-Trade-Effekt. Der vorliegende Beitrag präsentiert Ergebnisse für das Jahr 2021. Demnach musste die...

We develop a theory and an empirical strategy to estimate the welfare gains from trade in economies with frictional local labor markets. We obtain a welfare formula that nests several standard market structures and features an additional adjustment margin, via the employment rate. To obtain...

This paper quantifies the value of US highways. We develop a multisector general equilibrium model with many locations in the United States (i.e., counties) and many countries. In the model, producers choose shipping routes subject to domestic and international trade costs, endogenous...

We provide a quantitative analysis of the distributional effects of the 2018 increase in tariffs by the U.S. and its major trading partners. We build a trade model with incomplete asset markets and households that are heterogeneous in their age, income, wealth and labor skill. When tariff...

This paper emphasizes the different nature of cross border liberalization in network related services, such as telecoms, compared to liberalization in goods. In the presence of network externalities, it argues that if two disjoint country service networks involving a small and large country are...
