Quantitative Trade Restrictions in Unionized Economies

This paper models the interactions of a labor union and a monopoly firm under an import quota in a small open economy. The distorted equilibrium is depicted in a diagram, in which wages and employment in both sectors, and the monopoly rent, can be identified. The imposition of an import quota in the unionized sector reduces monopoly rent, union employment, and wages in both sectors, compared with the case of autarky. In addition, the paper presents several surprising comparative statics results. For instance, an increase in the world price causes the protected (i.e., "wrong") sector to shrink, wages to decrease, and national income to rise if the initial world price is low.     

Endogenous Debt Constraints in Lifecycle Economies

We characterize competitive equilibria with perfect foresight in a deterministic, three-period pure-exchange overlapping generations economy with perfect information and no commitment to loan contracts. Commitment is replaced by an enforcement mechanism that excludes defaulters from asset markets for one period. For hump-shaped endowment profiles, young individuals face endogenous debt constraints that ration current consumption. Changes in current and future yields affect these constraints, inducing an additional income effect on rationed household demand that makes current and future consumption complements. This mechanism can lead to multiple steady states, persistent indeterminacy and regime switching. We show that sensitivity to shocks and complex dynamic behaviour are consistent with endogenous debt limits but not with exogenous liquidity constraints.     

Business Cycles Between Developed and Developing Economies

This paper compares the stylized facts of international real business cycles between developed and developing countries. A two-sector two-country real business cycles model is constructed to examine the cyclical behaviors of domestic as well as international macroeconomic variables, and to evaluate the model's consistency with empirical observations. The model predicts correctly that consumption, investment, and saving are procyclical, while the trading balance/output ratio is countercyclical. There exist, however, some discrepancies between the model and the data.     

Analyzing the System of Preferential Tariffs for Least Developed Countries

This paper analyzes the rents available from non‐reciprocal preferential tariffs for least developed countries (LDCs) on all exports to the quad countries at the tariff line level. Most of the rents come from the European Union (EU) in clothing and textiles, while the USA and Canada offer few rents and charge significant tariffs to LDCs. We develop a dual economy labor market model that generates an income distribution and simulates the distributional effects of preferences. We find that the benefits of the preferences outweigh any adverse distributional effects. Relative inequality may increase with preferences in some cases, but absolute incomes increase in every case. We conclude that in the absence of multilateral liberalization, preferences are beneficial to some LDCs and expansion of preferences is desirable. In the event of multilateral liberalization, an import subsidy scheme that maintains the rents is the most desirable outcome.     

Offshoring and Trade Balance in Developed and Emerging Economies

This paper analyzes the effects of off‐shore outsourcing for international trade, especially for the emerging and poor economies, in a two‐sector specific factor model, with a nontraded good being one of the sectors. The phenomenon of offshoring is modeled by incorporating the reduced use of domestic labor in the production function. This is regarded as a characteristic feature of offshoring in the literature. We find that increased offshoring leads to an increase in the relative price of the nontraded good. Given that this relative price can be interpreted as the real exchange rate, increased offshoring leads to exchange rate appreciation. This suggests that offshoring actually makes the goods and services from the emerging economies more competitive in the world market, and thus can be a contributory factor in the positive trade balance experienced by many emerging economies since early 2000s.     

汇率制度与货币政策——发展中国家和小国经济的思考

本文中,我们将研究在资本市场对外开放及汇率固定条件下货币政策的管理机制问题。我们的目标是探讨货币政策能否在此种情况下继续独立而有效地稳定国内经济。为此,我们建议两种制度上的约束。给定这些约束,我们证明货币政策仍然有效。同时,本文讨论了此种制度选择对发展中国家和小国经济的意义。     

发达经济体农业风险管理体系建设经验与启示

农业风险管理体系是综合协调"政府—市场—组织"关系,由农业微观经济主体利用金融工具与合作组织,主动管理市场风险和生产风险。经过长期发展,在发达经济体逐渐形成的农业风险管理体系中,政府已日益倾向于减少对农业风险的直接干预,而是引导农业经营主体综合利用远期合同、期货、期权、保险来管理市场风险。这一发展趋势为我国农业风险管理实践和构建农业风险管理体系提供了全新思路。     

The Growth Crisis of Germany: A Blueprint of the Developed Economies

Germany has realized tremendous growth rates in the aftermath of the Second World War. Since the early 1970s, growth rates declined and settled down at a more or less constant rate of 2% per year, only to experience a renewed negative trend around the early 2000s. Estimating GMM growth models in a panel of 187 countries between 1970 and 2010, we illustrate that large parts of historical welfare increases have emerged due to conditional convergence, human capital accumulation, and innovation activity. Whereas conditional convergence was the main driver behind the extraordinary postwar growth rates in Germany, human capital accumulation in Germany currently lags behind the average level of most developed countries. While this may explain the moderate position of Germany in the group of the 25 richest countries, the developed countries on their part are experiencing a period of below-average GDP growth. In nearly all advanced economies, growth reveals a downward trend since the turn of the millennium. We argue that this decline must be traced back to a general lack of radically new ideas in the world economy. The explanation of the German growth crisis may thus be considered a blueprint of the situation in developed economies.     

发达和发展中经济体对华贸易救济的比较研究

本文在对发达经济体和发展中经济体对华贸易救济的特征差异进行分析的基础上,运用贸易救济指控指数和贸易救济涉案金额指数两项指标,进一步分析了其对中国出口贸易影响的差异,得出的结论是:发达经济体和发展中经济体在立案数量、措施选取、涉案行业、涉案金额、案件执行率和诉诸WTO等方面呈现出明显的特征差异,相对其在中国出口贸易中的地位而言,发展中经济体的贸易救济对中国出口贸易的影响大于发达经济体。     

发达经济体货币政策转向与新兴国家资本流入逆转

由于经济状况的好转,美国、欧元区和英国等发达经济体不断推进其货币政策回归正常,改变自2008年金融危机以来实行的量化宽松政策,发达经济体货币政策正在发生转向。在此背景下,文章利用PVAR模型实证分析了发达经济体货币政策转向是否会导致流入新兴国家的国际资本锐减,进而引发资本流入逆转。研究结果显示,发达经济体货币政策转向对新兴国家跨境资本流动的负面影响有限,新兴国家资本流入减少的幅度远低于资本流入逆转的阀值。与新兴国家的平均状况相比,低经济增长和弱资本管制新兴国家受到了更多来自发达经济体货币政策转向的冲击,但这些国家资本流入减少的幅度依然低于资本流入逆转的阀值。     

The Transition to Market Economies in an Endogenous Growth Model with Altruistic Agents

This paper considers an endogenous transition from a self-sufficient traditional economy to a market economy and its consequences on fertility and growth. The transition can occur if private intergenerational transfers are unable to secure old-age consumption as adequately as savings on capital markets; otherwise individuals stay in the traditional economy unless the mass-production technology in the market economy is sufficiently more advanced than individually accessible technologies. Markets emerge only if per capita output exceeds a certain level given a fixed cost of forming markets. The transition reduces fertility and promotes growth under plausible restrictions.

The Losses from Trade Restrictions: Policy Dynamics with Firm Selection and Endogenous Markup

In this paper, I explore the aggregate effects of trade restrictions in a two‐country, dynamic, general equilibrium (DGE) model with firm selection and variable adjustment of markup. As a response to the trade collapse in the global crisis of 2008 and 2009, temporary trade restrictions have emerged in several countries. With analyzing the dynamics of a negative macroeconomic shock in the home economy first, and the subsequent introduction of trade restrictions in the foreign economy second, I show that both economies are in a worse position than they were during the economic downturn. The follow‐ups to the recession and trade restrictions are investigated through three mechanisms: (1) variable markup as a new avenue of increasing competitive pressure for producers (e.g. more competitive firms lower their markups); (2) average individual firms' specific productivity cut‐off, which induces their optimum export choice (e.g. an increase in the export productivity cut‐off means exporting becomes more difficult than before.); and (3) the movement of international relative prices (e.g. the real exchange rate and terms of trade).     

The GDP Value of Twentieth‐Century Health Improvements in Developed Economies: Initial Estimates for England

Economists are aware that conventional measures of national income do not capture everything that is important to individuals. In particular, the value of huge improvements in health over the twentieth century has gone uncalculated. Usher and Nordhaus have emphasized the virtues of including mortality improvements in some form of extended national income measure. This article therefore sets out a methodology that can be used to calculate the value of mortality and morbidity improvements. The results for England indicate that the value of health improvements in developed economies have added at least 0.3 percent per annum to twentieth‐century GDP growth rates. The results demonstrate that those interested in understanding improvements in economic welfare need to pay much more attention to improvements in health.     

Relational Contracting in Developed Economies: Lessons From Slot Exchanges in the US Airline Industry

This paper highlights the widespread use of relational contracting in developed economies. While the number of empirical studies on relational practices in developing countries is increasing rapidly, evidence from industries and countries characterised by strong institutions is lagging behind due to data constraints. We argue that technological progress and strong institutions do not diminish the use of relational contracting, and use the US airline industry as a case in point. In particular, we discuss a number of factors (including transaction complexity, existence of collaborative relationships and data availability) that make this industry an ideal setting to study relational contracting in a developed economy. Moreover, we argue that other industries in developed countries share the properties of the US airline industry and, hence, can be used as a basis to investigate relational contracting in future work.     

The Real Exchange Rate in Small, Open, Developed Economies: Evidence from Cointegration Analysis

We examine the effects of the terms of trade and the expected real interest rate differential on the real exchange rate in small, open, developed economies. We employ cointegration analysis to search for long-term linkages. We find that while both the terms of trade and the expected real interest rate differentials affect the real exchange rate in the long run, the role of the terms of trade generally proves more consistent. The speed of adjustment for the expected real interest rate differential in the error-correction model, however, is quantitatively larger than it is for the terms of trade.     

The Impact of Ageing and the Speed of Ageing on the Economic Growth of Least Developed,Emerging and Developed Countries, 1990–2013

Studies relating ageing and countries’ economic performance address mostly developed economies. However, extant studies demonstrate that less developed countries (LDC) and emerging economies (EE) are reaching the transition process faster than those from developed regions, which renders the speed of ageing, besides ageing, a critical variable to explore in this context. Comparing system dynamic panel data estimations for 40 LDC, 19 EE and 28 developed countries (DC), between 1990 and 2013, we uncovered that ageing is detrimental to countries’ economic growth, with noticeable nuances depending on countries’ development level. The current level of ageing significantly and negatively impacts on DC's growth but not on that of LDC or EE. For these latter groups, the most relevant issue is the speed of ageing. The current annual growth of old age dependency ratio significantly diminishes EE's growth prospects whereas the lagged annual growth of the ageing index and the old age dependency ratio significantly curtails LDC's growth. Such results emphasize the need for urgent public policies that might mitigate the imbalance in LDCs’ age structure before the speed of ageing leads LDCs to become even much poorer.     

Economic growth,exports and foreign direct investment in Least Developed Countries: A panel Granger causality analysis

This paper investigates potential Granger causality among the real GDP, real exports and inward FDI in Least Developed Countries for the period between 1970 and 2009. A new panel-data approach developed in Kónya (2006) [Kónya (2006), Exports and growth: Granger causality analysis on OECD countries with a panel data approach, Economic Modelling, 23, 978–992] which is based on SUR systems and Wald tests with country specific bootstrap critical values has been employed. The results indicate direct, one-period-ahead, unidirectional causality from exports to GDP in Haiti, Rwanda and Sierra Leone, and from GDP to exports in Angola, Chad and Zambia. Considering the FDI–Growth nexus, there is evidence of FDI Granger-causing GDP in Benin and Togo, and GDP Granger-causing FDI in Burkina Faso, Gambia, Madagascar and Malawi. While studying EXP–FDI relations, this paper finds that the causality is from FDI to real exports in Benin, Chad, Haiti, Mauritania, Niger, Togo and Yemen, and from real exports to FDI in Haiti, Madagascar, Mauritania, Malawi, Rwanda, Senegal and Zambia.     

Business Cycle Accounting for Peripheral European Economies

Using the Business Cycle Accounting methodology, this paper analyzes the dynamics of the EMU‐periphery economies before and during what was called the sovereign debt crisis. TFP dynamics and the labor wedge explain most of the dynamics before and during the crisis. The bond wedge, corresponding to the risk premium, made a low contribution, moving counter‐cyclically. The capital wedge made a modest contribution to the fall in output during the crisis. Additional evidence links the dynamics of the TFP and the labor wedge with changes in the interest rates and a spike in import prices at the onset of the crisis, corresponding to the general mechanisms of the large capital inflows, in the wake of the introduction of the Euro, followed by sudden stops.     

高校扩招过程中的规模经济和范围经济

一、模型界定:多产出二次型模型及其简略探讨 所谓规模经济,一般界定为初始阶段,厂商由于扩大生产规模而使经济效益得到提高,这叫规模经济;而当生产扩张到一定规模以后,厂商继续扩大生产规模,会导致经济效益下降,这叫规模不经济。范围经济理论的主要思想是,如果联合生产几种产出的支出比分别生产它们的支出要少,那么就称联合生产存在范围经济。高校扩招过程中存在的规模经济和范围经济现象是两种理论得以应用的基础。
