Network externalities,transport costs,and tariffs

This article formulates a reciprocal market model of international duopoly with network externalities to reconsider welfare effects of reductions in transport costs and tariffs. Depending on the magnitude of network externalities, we show two possibilities. One of them, which emerges under strong network externalities, illustrates that freer trade unambiguously improves welfare for any initial level of trade barriers. This finding provides an affirmative evaluation of freer trade.     

Informality,tariffs and wealth

This article analyzes the interaction between changes in tariff protection, informality, inequality and aggregate income. First, we describe some new empirical evidence on informality, the formal/informal wage gap and trade openness in Latin American countries. Then we present a simple model characterized by three (empirically based) assumptions: (1) agents consume both formal and informal goods; (2) the government uses tariff revenues to purchase formal goods; (3) informality is a voluntary phenomenon. The model predicts that tariff reduction increases informality and wage inequality and that the maximization of income requires a positive level of tariff protection. The model's results are shown to be consistent with the empirical evidence concerning Latin American countries.     

Factor tariffs and income

This article examines a tariff on an imported factor of production in a small, open economy with two domestic factors. Suppose the imported factor is intensive in export production, and labor in import competing production. The factor tariff would reduce export production and trade, but raise the wage. The flexibility afforded by the three factors raises the possibility that import spending might fall more than the decrease in output. That is, the factor tariff could raise income. Inelastic demand for the imported factor and a high labor share of income favor increased income.     

Trade diversion and declining tariffs: evidence from Mercosur

This paper empirically examines the alternative posed by Richardson [J. Intern. Econ. 34 (1993) 39] to the traditional view that trade integration may exacerbate inefficiencies. Richardson's hypothesis boldly predicts that trade diversion (and trade creation) may actually cause tariffs to decline! The hypothesis is fundamentally attributable to the presence of a political component in the governments' objective functions. A cross-sectionally rich data set on trade and tariffs from the Mercosur-pact countries, primarily Argentina, is used. The evidence yields surprising conclusions about the validity of endogenous tariff determination in models of trade integration.     

Non-equivalent pass-through of anti-dumping duties,countervailing duties and import tariffs

We directly compare the short-run pass-through of tariffs, anti-dumping (AD) duties and countervailing (CV) duties into US import prices. Consistent with the theoretical predictions, we find clear pattern of non-equivalence in import price reaction to the three duty types, with the most notable difference detected between AD duties and tariffs. According to our estimates, a tariff rate would have to be approximately two times higher than an AD duty rate in order to have the same effect on the delivered import price.     

Price equivalent tariffs and quotas under a domestic monopoly

Price-equivalent import tariffs and quotas are compared when domestic production is controlled by a monopolist, say an agricultural marketing board with the power to restrict domestic supply, under endogenous terms of trade. Welfare comparisons boil down to sourcing costs comparisons. Quotas tend to dominate at high domestic prices, ad valorem tariffs at intermediate prices and specific tariffs at low domestic prices. Welfare maxima are achieved with more restrictive policies than under perfect competition. These results rationalize separate negotiations for sensitive products in the Doha Round and the setting of tariff-rate quotas that mimic import quotas for these products. Finally, in ascertaining the robustness of our policy ranking to the choice of variable anchoring the comparisons, we found that specific tariffs unambiguously dominate ad valorem tariffs and quotas when government revenue or imports anchor the comparisons. However, some quota revenues and import levels cannot be achieved with tariffs.     

Public inputs and land taxes in a small open economy

In this paper we examine the issues of gains from trade and the welfare effects of trade policies in the presence of public inputs. Based on the formulation of Negishi (Journal of Public Economics 2 (1973), 231–40), we assume that public inputs are financed by a land tax scheme. We show that the welfare effects of trade policies and the desirability of trade depend crucially on the rules of public input provision reflecting different conjectures of the government.     

Factor allocation,economic growth and unbalanced regional development in China

On the basis of development accounting techniques and a factor misallocation framework, we use panel data of 30 Chinese provinces from 2000 to 2013 to assess how factor allocation affects economic growth and unbalanced regional development in China. In particular, we decompose economic growth into three parts, namely sector productivity (SP ), factor market efficiency (FME ) and factor endowment (FE ). We then conduct counterfactual analyses to investigate the short and long‐run roles of factor allocation in the income distribution across provinces. The results show that SP , FME and FE can explain 23%, 8.5% and 68.5% of economic growth, while labour, capital and energy reallocation account for aggregate productivity growth of about 47%, −4.8% and −0.1%. Furthermore, when the factors are efficiently allocated, transferring labour (capital, energy) from agriculture (service, industry) to the other sectors will increase the income per capita by 29.5% and 42.5% in the short and long term. Meanwhile, efficient factor allocation accounts for 32% and 29.7% of aggregate productivity and reduces the income variation across provinces by 25.5% and 23% in the short and long run, respectively.     

The simultaneous evolution of economic growth,financial development,and trade openness

This article empirically investigates the interactions among economic growth, financial development, and trade openness through simultaneous equation systems. The identification and estimation of the systems rely on the methodology of identification through heteroskedasticity. The empirical results show that each of the three variables interacts in important ways. When controlling for the reverse causation, trade promotes economic growth in high-income, low-inflation, and nonagricultural countries but has a negative impact on growth in countries with the opposite attributes. Similarly, when accounting for the feedbacks from growth, banks and stock markets have different impacts on economic growth. While banking development is detrimental to output growth, stock market development is more favorable to growth in high-income, low-inflation, and nonagricultural countries. The data also reveal coexistence of a positive effect of financial development on trade and a negative effect of trade on financial development in poorer countries. In richer countries, financial development stimulates trade openness whereas trade has an ambiguous impact on financial development.     

Product development,imitation and economic growth: A note

Abstract

A dynamic North – South general equilibrium model of international product cycle is presented in this paper. The qualitative effects of strengthening intellectual property rights (IPR) on the balanced growth rate of the world economy is studied in two alternative cases: (i) imitation is direct from North to South; (ii) multinationalization is the channel of product transfer.     

A dynamic analysis of the impacts of export taxes: The case of Argentinean soy and beef markets

Argentina plays an important role in the global soy market as one of the world's leading exporters of soy products. In an effort to shift its agricultural sector's focus to value‐added exports and to raise revenue, Argentina's government has maintained a regime of differential export taxes on soy products. In addition to soy products, Argentina is a major producer, consumer and exporter of beef. However, over the last decade it has relinquished much of its world market share as its beef exports have fallen because the government has periodically imposed a ban on exports of beef along with maintaining an export tax. As the soy and livestock sectors are inextricably linked, owing to both industries’ intensive land use and the utilisation of soymeal as a feed supplement for cattle, trade policies in one sector have pronounced cross‐sectoral impacts. This study develops a theoretical model of these different sectors and trade policies, incorporating the dynamic decisions of cattle stock management. The model is calibrated to real‐world data on the Argentinean economy, and the impacts of trade liberalisation are quantified. Key results show modelling the various intersectoral linkages and the dynamic implications of cattle stock is essential for obtaining accurate estimates.     

Tourism development,environmental pollution and economic growth: A theoretical analysis

We develop a two-sector dynamic model of a less-developed economy with an imported traded good sector and with a non-traded tourism service sector serving international tourists. Revenue earned from tourism finances imports. The model takes care of the negative effect of tourism development on environmental pollution. Environmental quality and capital stock accumulates over time. We analyse comparative steady-state effects and show that tourism development raises the level of capital stock as well as national income but lowers the quality of environment in the new steady-state equilibrium leading to a relative expansion (contraction) of the capital (labour) intensive non-tourism (tourism) sector. Pollution abatement policy produces a completely opposite effect; and so tourism development policies are to be accompanied by pollution abatement policies in order to ensure green growth.     

Entrepreneurship,economic development and institutions

This paper is an introduction to the special issue from the 3rd Global Entrepreneurship Monitor Research Conference held in Washington, D.C., in 2008. The paper has three objectives. First, to discuss the importance of the three stages of economic development, the factor-driven stage, the efficiency-driven stage and the innovation-driven stage. Second, to examine the empirical evidence on the relationship between stages of economic development and entrepreneurship. Third, to present a summary of the papers in the context of the theory.

Optimal pricing, production rate, and quality under learning effects

This study investigates the marketing and production problem for a monopolist firm where price, quality and production rate are simultaneous dynamic decision variables under the condition of a dynamic demand that depends on price, quality and cumulative sales. The formulated continuous profit maximization model follows the steps for dynamic optimization to derive optimal price, quality and production policies, wherein a unit production cost that decreases with cumulative production reflects the cost learning effect. Through the differentiable multiplicatively separable demand function, this study analyzes optimal trajectories for determining price, quality, and production rate. The results specify several optimal policies and policy makers would gain insight into the consequence of their decisions that otherwise might have been obscured by sub-optimal analysis.     

Trade protection and tax evasion: Evidence from Kenya,Mauritius, and Nigeria

We examine the effect of trade protection rates on evasion in three African countries Kenya, Mauritius, and Nigeria. In capturing the effect of trade protection on tariff evasion, we use a much improved measure of trade protection (MAcMap-HS6 2001 and 2004). For two of these countries, this dataset allows the novelty of using variation in trade protection across product, time, and trading partners leading to significantly refined estimates of evasion elasticity relative to existing studies on tariff evasion. We find a robust evidence for positive elasticity of evasion with respect to tariffs in Kenya and Nigeria with relatively weaker evidence for Mauritius. Our results match the rankings of countries in institutional quality. Greater responsiveness of evasion to the level of tariffs is established in Nigeria (comparatively weak institutional quality) vis-à-vis Kenya, and in Kenya vis-à-vis Mauritius (comparatively good institutional quality). This pattern is preserved even when focusing on same set of trading partners and same set of imported products for the three countries. This result is robust to controlling for protection on related products (that creates incentives/ opportunities for evasion) and also for degree of differentiation of the product and some other characteristics.     

基于经济增长的中国最优消费规模:1978—2006

中国长期实行"重投资、轻消费"的政策,消费率一直偏低。以限制消费为代价的经济增长不仅无法实现社会福利最大化和居民效用最大化,而且也是不可持续的。消费不足导致经济增长乏力,然而消费过度会导致投资不足从而阻碍经济增长,因此经济中存在最优的消费规模。在检验消费规模和经济增长关系的基础上,建立消费的内生增长模型,利用1978—2006年间29年的经验数据,求得中国消费率的最优值为66.46%,据以提出扩大消费以扩大内需、促进经济增长的政策建议。     

Quick and easy choice sets: Constructing optimal and nearly optimal stated choice experiments

In this paper we compare a number of common strategies for constructing discrete choice experiments. Two of the strategies, including one based on theoretical constructions for optimal discrete choice experiments, produce designs that are better than those that come about from random grouping and from using the L^MA construction. A simple account of this theoretical construction is given.

Segmented asset markets and optimal exchange rate regimes

This paper revisits the issue of the optimal exchange rate regime in a flexible price environment. The key innovation is that we analyze this question in the context of environments where only a fraction of agents participate in asset market transactions (i.e., asset markets are segmented). Under this friction alternative exchange rate regimes have different implications for real allocations in the economy. In the context of this environment we show that flexible exchange rates are optimal under monetary shocks and fixed exchange rates are optimal under real shocks.     

Fertility,intergenerational transfers and economic development

This paper develops a model of endogenous growth where agents are altruistic and value both the utilities of their parent and of their children. Individuals endogenously choose the number of their children, and arbitrate between financing education, leaving them some bequest and offering some gift to their parents. We establish the existence of three types of long run regime. Starting from a low level of human capital, an economy converges towards a stationary state associated with a constant output per worker, a high level of fertility and ascendant transfers. If the initial level of human capital is not too low, another stationary state jointly exists with a lower level of fertility and no transfer. Finally, starting from a high level of human capital, the economy experiences a steady growth of output per worker associated with a low fertility level and descendant transfers. We then assume that an economy is initially in the stationary underdevelopment regime with ascendant transfers, and we study the power of different policies to push the economy toward the growth regime. We successively consider a fertility control policy, an education subsidies policy, and the introduction of a pension system for the elderly.
