Market access and welfare effects of free trade areas without rules of origin by Jiandong Ju( Book )
19 editions published in 1996 in English and held by 72 libraries worldwide
The market access and welfare effects of Free Trade Areas (FTAs) without Rules of Origin (ROOs) are studied. We consider both the final and intermediate goods markets and their interlinkage. The FTA weakly reduces all tariffs and prices within the FTA. This raises quantity demanded and reduces quantity supplied for both the final and intermediate goods, thereby raising imports. This is the classic trade creation effect and is welfare improving. We identify two additional effects which work in the opposite direction and identify conditions under which these welfare reducing, import reducing effects dominate
Evaluating trade reform using ex-post criteria by Jiandong Ju( Book )
13 editions published in 1997 in English and held by 67 libraries worldwide
In contrast to existing work which takes an ex-ante approach and looks for policy prescriptions which yield welfare improvements, we take an ex-post approach. We ask whether there are indicators which show whether welfare has risen or not in the wake of a reform. That is, we look for evidence of welfare improvements in outcome space. Necessary and sufficient conditions for welfare improving trade reform are derived. These conditions are shown to be useful in evaluating Free Trade Areas and in reforming Article XXIV of GATT

Firm behavior and market access in a free trade area with rules of origin by Jiandong Ju( Book )
12 editions published between 1998 and 1999 in English and held by 66 libraries worldwide
We develop a model to study the behavior of firms in a Free Trade Area with Rules of Origin and the consequences of this behavior on the market equilibrium and outcome. We show that firms will choose to specialize, and that an FTA with strict ROOs on the intermediate good raises imports and hence improves market access in the final good market reduces imports and hence harms market access in the intermediate good market. More restrictive ROOs on the final good first raise and then lower imports of the final good lower than raise imports of the intermediate good. Their turning point is common so that imports of the final good are maximized and imports of the intermediate good are minimized at a common level of restrictiveness of the rules of origin. We show that our model can be reinterpreted to show that more restrictive ROOs on the final good first improves and then harms the fortunes of labor, and to cast light on a particular policy to improve market access. Other problems with a similar structure could also be analyzed using our techniques; we expect similar results
A solution to two paradoxes of international capital flows by Jiandong Ju( Book )
24 editions published in 2006 in English and held by 50 libraries worldwide
International capital flows from rich to poor countries can be regarded as either too low (the Lucas paradox in a one-sector model) or too high (when compared with the logic of factor price equalization in a two-sector model). To resolve the paradoxes, we introduce a non-neoclassical model which features financial contracts and firm heterogeneity. In our model, free patterns of gross capital flow emerge as a function of the quality of the financial system and the level of protection for property rights(i.e., the risk of expropriation. A poor country with an inefficient financial system but a low expropriation risk may simultaneously experience an outflow of financial capital but an inflow of foreign direct investment (FDI), resulting in a small net flow
Domestic institutions and the bypass effect of financial globalization by Jiandong Ju( Book )
15 editions published between 2007 and 2010 in English and held by 36 libraries worldwide
"This paper proposes a simple model to study the relationship between domestic institutions - financial system, corporate governance, and property rights protection - and patterns of international capital flows. It studies conditions under which financial globalization can be a substitute for reforms of domestic financial system. Inefficient financial system and poor corporate governance in a country may be completely bypassed by two-way capital flows in which domestic savings leave the country in the form of financial capital outflows but domestic investment takes place via inward foreign direct investment. While financial globalization always improves the welfare of a developed country with a good financial system, its effect is ambiguous for a developing country with an inefficient financial sector/poor corporate governance. However, the net effect for a developing country is more likely to be positive, the stronger its property rights protection. This is consistent with the observation that developed countries are often more enthusiastic about capital account liberalization around the world than many developing countries. A noteworthy feature of this theory is that financial and property rights institutions can have different effects on capital flows."--Abstract
Endowment versus finance : a wooden barrel theory of international trade by Jiandong Ju( Book )
11 editions published in 2005 in English and Undetermined and held by 30 libraries worldwide
This paper develops a theory of international trade in which financial development and factor endowments jointly determine comparative advantage. We apply the financial contract model of Holmstrom and Tirole (1998) to the Heckscher-Ohlin-Samuelson (HOS) model in which firms' dependence on external finance is endogenous, and the demand for external finance is constrained by financial development. The theory nests HOS model as a special case. A key result that emerges is what we call the law of a wooden barrel: if the external finance constraint is binding, then further financial development will increase the output of the industry more dependent on external finance, and decrease the output of the other industry. It is shown that financial development makes both labor and unemployed capital better off, but incumbent capital worse off. Therefore, financial development depends on the relative strength of political forces among labor, unemployed capital owners, and incumbent capital owners. If only the capital constraint is binding, on the other hand, the standard HOS predictions will apply
On the connection between intra-temporal and intertemporal trade by Jiandong Ju( Book )
12 editions published between 2011 and 2012 in English and held by 22 libraries worldwide
Sticky (or slow-adjusting) current accounts are observed for many countries. This paper explores the role of domestic factor market flexibility in understanding the phenomenon. To do so, we consider multiple tradable sectors with different factor intensities and allow substitution between intertemporal trade (current account adjustment) and intra-temporal trade (goods trade) in a dynamic general equilibrium model. An economy's response to a shock generally involves a combination of a change in the composition of goods trade and a change in the current account. Flexible factor markets reduce the need for the current account to adjust. On the other hand, the more rigid the factor markets, the larger the size of current account adjustment relative to the volume of goods trade, and the slower the speed of adjustment of the current account towards its long-run equilibrium. We present empirical evidence in support of the theory
Current account adjustment : some new theory and evidence by Jiandong Ju( Book )
9 editions published in 2007 in English and held by 20 libraries worldwide
This paper aims to provide a theory of current account adjustment that generalizes the textbook version of the intertemporal approach to current account and places domestic labor market institutions at the center stage. In general, in response to a shock, an economy adjusts through a combination of a change in the composition of goods trade (i.e., intra-temporal trade channel) and a change in the current account (i.e., intertemporal trade channel). The more rigid the labor market, the slower the speed of adjustment of the current account towards its long-run equilibrium. Three pieces of evidence are provided that are consistent with the theory
Trade reforms and current account imbalances : when does the general equilibrium effect overturn a partial equilibrium intuition? by Jiandong Ju( Book )
11 editions published between 2012 and 2013 in English and held by 18 libraries worldwide
While a reduction in import barriers in a partial equilibrium may be thought to lead to an increase in imports and a reduction in trade surplus, the general equilibrium effect can go in the opposite direction. We study how trade reforms affect current accounts by embedding a modified Heckscher-Ohlin structure and an endogenous discount factor into an intertemporal model of current account. We show that trade liberalizations in a developing country would generally lead to capital outflow. In contrast, trade liberalizations in a developed country would result in capital inflow. Thus, efficient trade reforms can contribute to global current account imbalances, but these imbalances do not need policy "corrections."
When is quality of financial system a source of comparative advantage? by Jiandong Ju( Book )
10 editions published in 2008 in English and held by 14 libraries worldwide
Does finance follow the real economy, or the other way around? This paper unites the two competing schools of thought in a general equilibrium framework. Our key result is that there are threshold effects defined by a set of deep institutional parameters (cost of financial intermediation, quality of corporate governance, and level of property rights protection) which can be used to separate economies of high-quality institutions from those of low-quality institutions. On one hand, for economies with high-quality institutions, the view that finance follows the real economy is essentially correct. Equilibrium output and prices are determined by factor endowment. Further improvement in the institutions does not affect patterns of output. On the other hand, for economies with low-quality institutions, the view that finance is a key driver of the real economy is essentially correct. Not only is finance a source of comparative advantage, but an increase in capital endowment has no effect on outputs and prices. Our model extends a standard one-sector, partial equilibrium model of corporate finance to a multi-sector, general equilibrium analysis. Surprisingly, but consistent with data, we show that the size of financial markets (relative to GDP) does not change monotonically with either the quality of institutions or with the factor endowment. Free trade may reduce the aggregate income of an economy with low-quality institutions. Financial capital tends to flow from economies with low-quality institutions to those with high-quality institutions
Endowment Structures, Industrial Dynamics, and Economic Growth by Jiandong Ju( file )
6 editions published between 2009 and 2012 in English and Undetermined and held by 5 libraries worldwide
This paper develops a dynamic general equilibrium model to explore industrial evolution and economic growth in a closed developing economy. The authors show that industries will endogenously upgrade toward the more capital-intensive ones as the capital endowment becomes more abundant. The model features a continuous inverse-V-shaped pattern of industrial evolution driven by capital accumulation: As the capital endowment reaches a certain threshold, a new industry appears, prospers, then declines and finally disappears. While the industry is declining, a more capital-intensive industry appears and booms, ad infinitum. Explicit solutions are obtained to fully characterize the whole dynamics of perpetual structural change and economic growth. Implications for industrial policies are discussed

Marshallian Externality, Industrial Upgrading, and Industrial Policies by Jiandong Ju( file )
6 editions published between 2011 and 2012 in English and Undetermined and held by 5 libraries worldwide
A growth model with multiple industries is developed to study how industries evolve as capital accumulates endogenously when each industry exhibits Marshallian externality (increasing returns to scale) and to explain why industrial policies sometimes succeed but sometimes fail. The authors show that, in the long run, the laissez-faire market equilibrium is Pareto optimal when the time discount rate is sufficiently small or sufficiently large. When the time discount rate is moderate, there exist multiple dynamic market equilibria with diverse patterns of industrial development. To achieve Pareto efficiency, it would require the government to identify the industry target consistent with the comparative advantage and to coordinate in a timely manner, possibly for multiple times. However, industrial policies may make people worse off than in the market equilibrium if the government picks an industry that deviates from the comparative advantage of the economy

Thermo-micromechanical damage models of airfield concrete pavement under high temperature loading by Hongwei Gong( Book )
2 editions published in 1998 in English and held by 1 library worldwide
Ordinary Portland Cement (OPC) is a widely used construction material. In airbase facilities, it is used to construct the runways and parking aprons. During the takeoff and landing of aircrafts, the high temperature exhaust has splashed to the concrete pavement from the modem vectored thrust engines (VTE) or auxiliary Power Unit (APU). The APU is a low-power has turbine that provides compressed air, from a load driven compressor, for starting the main engines and for operating auxiliary systems during ground maintenance. In particular, the exhaust gas temperature of a VTE could rapidly reach over 700 deg C, and the corresponding exhaust velocities could go beyond 1800 ft/s. The pavement is subjected to extremely rapid transient high temperature loadings as well as thermal cycles of heating and cooling. Figure 1.1 shows a typical damaged area in an F/A-18 parking apron. The origin of the problem is the F/A-18 auxiliary power unit, which is located at the bottom of the fuselage near the tail section. The exhaust gas temperature isotherms on the pavement top are almost circular and show a decrease along the radios. Chemical degradation of concrete due to hydraulic fluid, lubricating oils also contribute to the damage of concrete pavement. The U.S. Department of Defense has seen an increase in airfield concrete apron distress in the form of surface scaling when the aprons are exposed to cyclic heat, spilled lubricants, and/or hydraulic fluid (McVay, Smithson and Manzione, 1993). Chemical analysis of the damaged concrete reveals that the spilled fluid from the engines are undergoing hydrolysis (breakdown) accompanied by the consumption of calcium hydroxide, plus hydrated silicate and aluminate phases

Market Access and Welfare Effects of Piecemeal Policy Reform ( file )
2 editions published in 1997 in English and held by 0 libraries worldwide
In a situation where tariff reforms are being negotiated between two parties aims to raise its exports and the other aims to raise its welfare, tariff cuts must be in the interest" of at least one party. It is possible for the interests of the two sides to conflict. Conflict is certain" if the excess demand for exported goods does not respond to changes in the prices of imported" goods. In this case, any policy which raises imports must also reduce welfare."
