Two Ways of Estimating a Transport Model AgEcon
Jansson, Torbjorn.
In this article, it is shown how the parameters of a transport model can be estimated in a way that, in contrast to previously used methods, utilizes observations of regional prices as well as of trade costs. The proposed method uses bi-level programming to minimize a weighted least squares’ criterion under the restriction that the estimated parameters satisfy the Kuhn-Tucker conditions for an optimal solution of the transport model. We use Monte-Carlo simulations to trace out some properties of the estimator and compare it with a traditional calibration method. The analysis shows that the proposed technique estimates prices as well as trade costs more efficiently.

An Empirical Investigation of Interproduct Relationships Between Domestic and Imported Seafood in the U.S. AgEcon
Lee, Young-Jae; Kennedy, P. Lynn.
This study seeks to identify interproduct relationships between domestic catfish and a representative selection of imported seafood. In doing so, this study uses multivariate cointegration and structural analyses. Multivariate cointegration analysis suggests that six imported seafood product groupings form a common market with domestic catfish. Structural analysis reveals that 1) domestic and imported catfish are net and gross quantity substitutes; 2) domestic catfish and imported seafood are normal goods; 3) six imported seafood products are identified as gross quantity substitutes for domestic catfish; and 4) according to the derived Allais coefficients, interaction intensities of imported seafood for domestic catfish (from greatest to least) are as...

Gender Inequality and Trade AgEcon
Busse, Matthias; Spielmann, Christian.
The paper empirically explores the international linkages between gender inequality and trade flows of a sample of 92 developed and developing countries. The focus is on comparative advantage in labour-intensive manufactured goods. The results indicate that gender wage inequality is positively associated with comparative advantage in labour-intensive goods, that is, countries with a larger gender wage gap have higher exports of these goods. Also, gender inequality in labour force activity rates and educational attainment rates are negatively linked with comparative advantage in labour-intensive commodities.

Agricultural Trade and Freshwater Resources AgEcon
Reimer, Jeffrey J..
Approximately 75% of all water used by humans goes towards food production, much of which is traded internationally. This study formally models how this works in the case of crop agriculture, making use of recent advances in international trade theory and new data on the productivity by which countries use water for crop agriculture. The strength of the model lies in its ability to predict, when there is a shock to the system, how trade between pairs of specific countries changes for products that use water intensively. In one application of the model, international trade in final products is shown to be a means for countries to deal with short- and long-run shocks to water resources that are too big for one country to handle by itself in isolation. In...

Productivity, Geography, and the Export Decision of Chilean Farms AgEcon
Echeverria, Rodrigo; Gopinath, Munisamy.
This article analyzes the export participation of Chilean farms and the relative importance of farm-specific and geographic characteristics in this decision. An export behavior model is estimated using data on 8,284 Chilean farms and a two-stage conditional maximum likelihood procedure. Farm efficiency has a relatively stronger effect than the combined effect of geographic characteristics in increasing the probability of export participation. Farms with skilled (managerial) labor and in regions with higher human capital also have a relatively higher probability of producing for the export market. However, for geographic characteristics to positively affect export participation, farms must achieve a minimum level of efficiency.

The Export-Production Decision of Chilean Farmers: The Case of Blueberry Producers AgEcon
Echeverria, Rodrigo; Gopinath, Munisamy; Moreira, Victor H.; Cortes, Pedro.
This article analyzes the relative importance of producers’ attributes and farms’ geographical characteristics in the decision to produce an exportable good (blueberries) in the southern region of Chile. Using farm-level data, a logit model is estimated to identify factors influencing the export-production decision. Results show that the probability of producing blueberries increases with the educational level of producers (a proxy for productivity), the presence of irrigation and drainage systems, and the availability of labor. The last factor, which arises from the proximity to large and urbanized regions, has a stronger effect on the export-production decisions of Chilean farms than either farmers’ education or farms’ physical characteristics.

Effects of Price and Quality Differences in Source Differentiated Beef on Market Demand AgEcon
Lee, Young-Jae; Kennedy, P. Lynn.
In order to estimate demand elasticities of source differentiated beef in South Korea, this study used the quantity of an endogenous demand system derived through maximizing the economic welfare of market participants including local beef consumers and local and foreign beef suppliers. The demand system is then weighted with respect to quality adjustment parameters to identify the effects of quality differences in source differentiated beef on market demand. As implied by the high relative price of locally produced ‘‘Hanwoo’’ beef, substitutability between local and imported beef is shown to be very weak and the own price elasticity of South Korean beef is shown to be inelastic. Related to quality differences between source differentiated beef, South...

Path Interdependence Among Early and Late Bloomers in a Dynamic Heckscher-Ohlin Model AgEcon
Gaitan, Beatriz; Roe, Terry L..
The closed economy neoclassical growth model predicts convergence to a capital stock level that is independent of its initial level, suggesting that discrepancies in per capita income among the world’s economies should largely disappear in the long-run. This paper shows that international trade among countries differing only in their level of initial capital is sufficient to generate long-run income differences across countries. The long-run level of capital of the country most initially endowed with capital is shown to exceed the level of capital otherwise obtained in autarchy while the country least endowed converges to a capital stock lower than would otherwise be obtained in autarchy.

Efficient choice among domestic and trade policies in the Grossman-Helpman Interest-Group Model AgEcon
Schleich, Joachim; Orden, David.
This paper generalizes the recent political economy model of Helpman and Grossman in which contributions by producer lobbies and government decisions about trade policies are modeled as a common agency game. We allow the government to choose among domestic as well as trade interventions. When production and trade policies are available, the equilibrium production policies serve the lobbies while the trade policies reflect the country's international market power. When consumption and trade policies are available, tariffs and export subsidies are applied in a small-country model to serve the special interests, and the domestic policies are selected to restore consumer prices to world levels. In a large-country model, the optimal consumption and trade...

Gender Discrimination and the International Division of Labour AgEcon
Busse, Matthias; Spielmann, Christian.
The paper empirically explores the international economic effects of gender discrimination, namely the linkages of gender inequality with comparative advantage (trade) and foreign direct investment flows. It discusses different forms and the extent of gender discrimination across countries and presents the results of empirical tests of those linkages. The results indicate that gender inequality is positively associated with comparative advantage in unskilled-labour-intensive goods, that is, commodities where the impact of gender bias is likely to be felt most strongly. In contrast, foreign direct investment is negatively linked with gender inequality. These results even hold for relatively poor developing countries.

Agricultural Trade Liberalisation and Strategic Environmental Policy AgEcon
Glebe, Thilo W.; Latacz-Lohmann, Uwe.
We use an extended partial equilibrium trade model to derive optimal environmental policy responses to tariff reduction requirements and assess the impact of such policies on the welfare of trading partners. We find that countries which attribute preferential political weights to farmers' welfare have an incentive to implement environmental policies that deviate from the Pigouvian solution - even if production is not de facto linked to environmental externalities. We clarify the conditions under which trading partners do not gain from unilateral trade liberalisation if trade concessions are accompanied by strategic environmental policy changes. We postulate a role for the WTO in overseeing the process of domestic policy formulation.

Updated Arkansas Global Rice Model AgEcon
Wailes, Eric J.; Chavez, Eddie C..
The Arkansas Global Rice Model is based on a multi-country statistical simulation and econometric framework. The model consists of six sub regions. These regions are the U.S., South Asia, North Asia and the Middle East, the Americas, Africa and Europe. Each region comprises of several countries and each country model has a supply sector, a demand sector, a trade, stocks and price linkage equations. All equations used in this model were estimated using econometric procedures or identities. Estimates are based upon a set of explanatory variables including exogenous macroeconomic factors such as income, population, inflation rate, technology development, and especially, government determined policy variables which reflect the various mechanisms by which...

Why Governments Tax or Subsidize Trade: Evidence from Agriculture AgEcon
Gawande, Kishore; Hoekman, Bernard.
This paper empirically explores the political-economic determinants of why governments choose to tax or subsidize trade in agriculture. We use a new data set on nominal rates of assistance (NRA) across a number of commodities spanning the last five decades for 64 countries. NRAs measure the effect on domestic (relative to world) price of the quantitative and price-based instruments used to regulate agricultural markets. The data set admits consideration of both taxes and subsidies on exports and imports. We find that both economic and political variables play important roles in determining the within-variation in the NRA data. Based on our results we offer a number of data-driven exploratory hypotheses that can inform future theoretical and empirical...

GROWTH PATTERN, SUSTAINABILITY AND TRADE IN A LAND CONSTRAINED ECONOMY AgEcon
Irz, Xavier T.; Roe, Terry L..
This paper develops a two-sector model of growth where agriculture is considered explicitly. Key features of the model include: the reliance of agricultural production on a fixed but degrading resource base, the use by the farm sector of industrially produced inputs and differing rates of technological progress in the two sectors. On the demand side, the low income elasticity for food as well as the life-sustaining function of food consumption are recognized. In this simplified framework, the sustainability of growth can be related to the existence of a steady state reflecting the ability of the economy to feed its population. This property is used to identify the characteristics within and outside of agriculture conducive to the sustainability of a...

Agricultural Price Distortion and Stabilization: Stylized facts and Hypothesis Tests AgEcon
Masters, William A.; Garcia, Andres F..
This paper describes agricultural policy choices and tests some predictions of political economy theories. It begins with three broad stylized facts: governments tend to tax agriculture in poorer countries, and subsidize it in richer ones, tax both imports and exports more than nontradables, and tax more and subsidize less where there is more land per capita. We test a variety of political-economy explanations, finding results consistent with hypothesized effects of rural and urban constituents’ rational ignorance about small per-person effects, governance institutions’ control of rent-seeking by political leaders, governments’ revenue motive for taxation, and the role of time consistency in policy-making. We also find that larger groups obtain more...

Can a Preferential Trade Agreement Benefit Neighbor Countries without Compensating Them? AgEcon
Endoh, Masahiro; Hamada, Koichi; Shimomura, Koji.
PTAs are generally negotiated without any tariff concessions or transfers to non-member countries. Can such a PTA benefit the neighbors’ welfare? In a two-good competitive equilibrium model in the absence of an entrepot, a PTA without concessions to the outsider will hurt the outsider’s welfare when goods are normal. If one of the member countries is an entrepot, however, it definitely improves the neighbors’ welfare. In a multiple-good model, a PTA without concessions deteriorates the neighbors’ welfare, provided that all the goods are normal and substitutes, and that initial tariff levels are small.

The Impact of Financial Crises on Trade Flows: A Developing Country Perspective AgEcon
Macias, Jose Brambila; Massa, Isabella; Salois, Matthew J..
The global financial crisis has hit hard international trade that dropped below levels not seen since the Great Depression with disastrous consequences for the developing world. This paper estimates an extended gravity model of trade on a sample of 83 developing countries over the period 1990-2007 to shed light on how banking crises and global economic downturns affect bilateral exports flows from developing countries. In addition to traditional variables, we include a trade finance variable and foreign aid among the regressors. Differences between developing regions are taken into account. Our results show that (i) trade finance has a positive and significant impact on bilateral export flows in all developing regions except Latin America; (ii) foreign aid...

Enlargement of the European Union: A movement towards the optimal trade bloc size? AgEcon
Glebe, Thilo W..
This paper analyses how the enlargement of a trade bloc will affect national welfare. We establish a partial equilibrium model of a trade bloc either operating as a monopoly with a competitive fringe or facing a duopolistic game in production taxes/subsidies. Given this framework, we demonstrate how member countries’ welfare effects depend on their trade flow and the market power of the trade bloc. A numerical estimation of the effects of EU enlargement on the major grain crop markets suggests that welfare effects are negligible. Economic reasons are therefore unlikely to be a motivating force for further enlargement.
