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 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...

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...

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...

We consider a dynamic setting where two countries with competing claims to a resource/asset first arm and then choose whether to resolve their dispute through war or peacefully through settlement. War precludes international trade and can be destructive, but also locks gains and eliminates...

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 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...

We consider a dynamic setting where two countries with competing claims to a resource/asset first arm and then choose whether to resolve their dispute through war or peacefully through settlement. War precludes international trade and can be destructive, but also locks gains and eliminates...

Linder (1961) conjectured that taste differences could impede trade flows. We extend Krugman (1980) to allow for producers that face taste heterogeneity with volatile demand. Consumers are characterized by different taste over product attributes and idiosyncratic risk. Firms face a portfolio...

We consider a dynamic setting in which two sovereign states with overlapping ownership claims on a resource/asset first arm and then choose whether to resolve their dispute violently through war or peacefully through settlement. Both approaches depend on the states' military capacities, but...

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...

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...

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 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...

This paper shows how gains from trade are conditioned by love of variety, defined as the extent to which an additional product variety generates benefits in either final or intermediate consumption. We develop a multi-country, multi-sector gravity trade model where love of variety is...

We study the gains from trade in a model with oligopolistic competition, heterogeneous firms and innovation, and provide a formula to decompose the mechanism. The new insight we provide is that market concentration can be a welfare-relevant feature of market power above and beyond markup...

How does intranational factor mobility shape the welfare effects of a trade shock? I provide evidence that during WWI, a demand shock emanated from belligerent countries and affected neutral Spain. Within Spain, labor predominantly reallocated locally, while the most affected provinces...

This paper explores the role of wage fund as the basic source of credit, capital or finance in a dynamic Ricardian model, which consists of three classes of agents: the workers, the capitalist, and the producers of goods. We introduce and develop an elaborate dynamic wage fund model 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...

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...

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...

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 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,...

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...
