Trade and environment are essential issues closely related to the development of the national economy and the improvement of people’s livelihood in the new era. The Report to the 19th National Congress of the Communist Party of China (CPC) listed the construction of a strong trading power as an important part of building a modern economic system and pollution prevention and treatment as one of the three key battles to win the decisive victory of building a moderately prosperous society in all respects. However, the relationship between trade and environmental pollution is still very controversial in the existing literature, and there is a paucity of literature on the relationship between trade and environmental pollution based on micro data.

This paper merged China’s Firm-Level Pollution Database with China’s Industrial Enterprise Database and China’s industry tariff rates. Additionally, by virtue of the quasi-natural experiment of China’s accession to the World Trade Organization (WTO), a difference in difference (DID) model was constructed to alleviate the endogeneity issue.

According to the results, the trade barrier decrease (trade liberalization) significantly reduces the intensity of SO₂ emissions, a major pollutant of enterprises, as the intensity of SO₂ emissions decreased 2.16% for each unit decrease of the trade barrier. The analysis of the mechanisms shows that the SO₂ emission intensity of enterprises is mainly due to the decrease of enterprises’ pollution emission rather than the decrease of output, and the decrease of enterprises’ pollution emission is mainly caused by the enterprises’ cleaner production process rather than the end treatment of pollution emission. The decrease of coal use intensity is an important mechanism of the decrease of SO₂ emission intensity caused by the decrease of trade barriers. Among the technical effects of the change of the trade barrier affecting enterprises’ pollution emission, biased technical change rather than neutral technical change dominates.

The findings of this paper imply that expanding openness can enhance China’s social welfare not only through the economic growth mechanisms identified in the classical literature, but also through environmental improvements. This provides useful policy insights for promoting the construction of a strong trading power and winning the battle against pollution in the new era.

The purpose of the paper is to investigate the quantitative effect of import liberalization on tariff revenue in Ghana.

In an attempt to achieve the objective of the paper, a robust decomposition analytical approach was used to examine how different components of the sources of change in import tax contribute to changes in import tax revenue in Ghana.

The paper concludes that Ghana suffered some revenue loss from the liberalization by reducing the level of average official duty rates, but gained in revenue as a result of real currency depreciation.

It has been suggested that public policy should aim at determining and targeting the optimum level of the average official import duty rates, focus on the identification of the major sources of duty revenue leakage, and substitute sales taxes for tariffs to improve tax revenue sufficiently.

This paper makes explicit the contribution of alternative import policy features to changes in import tax revenue in Ghana.

This paper aims to examine the impact of stock market liberalization on efficiency of the stock markets in Latin America.

Daily stock indices from Latin American countries, including Brazil, Mexico, Chile, Peru, Jamaica and Trinidad and Tobago, are used in the analysis. To examine the impact of stock market liberalization on efficiency, the authors use several approaches, including the runs test, Chow–Denning multiple variation ratio test, Wright variance ratio test, the martingale hypothesis test and the stochastic dominance (SD) test, on the above Latin American stock market indices.

The authors find that stock market liberalization does not improve stock market efficiency in Latin America.

This investigation is among the first to examine the impact of stock market liberalization on the efficiency of the stock markets. It is among the first to examine the impact of stock market liberalization on the efficiency of the Latin American stock markets. It is also among the first to apply the martingale hypothesis test and a SD approach on issue about efficient market.

There is a large body of literature on the link between trade liberalisation, growth and poverty. However, less attention has been paid to the relationship between trade and regional disparities. The purpose of this paper is to identify and quantify the regional impacts of trade liberalisation, particularly in the war-affected regions and to understand to what extent trade reforms can contribute to the post-war recovery process and long-term economic and political stability in Sri Lanka.

The authors developed a single country multi-regional computable general equilibrium (CGE) model for the Sri Lankan economy to meet the need for a detailed country study as emphasised in the recent literature.

Both short-run and long-run results suggest that all regions including war-affected regions in the country gain from trade liberalisation, although gains are uneven across regions. Furthermore, the results suggest that war-affected regions gain more relative to some other regions in the long run.

According to the best of the authors’ knowledge within country regional impact of trade liberalisation using a multi-regional CGE model has never been attempted for Sri Lanka. The results of this study, even though based on Sri Lankan data, will be relevant to other developing countries engulfed in internal conflicts with regional economic disparities.

The purpose of this paper is to investigate the impact of liberalisations policies on income inequality in African countries. Examining whether the liberalisations policies have affected the income distribution of everyone equally or they only assist those who are already relatively well off; leaving the poor behind. The authors also examine how they affect income distribution in the various countries within the continent, and their effect on short and long runs?

First, The authors used the before and after comparison, to examine the response of the level of income inequality and the volatility of income inequality from the time that financial or trade liberalisations took place in each country. Next, the authors used the panel data techniques model for a sample of 26 African countries spanning the period 1996-2010 to investigate the effect of liberalisation policies on income distribution.

The authors find that financial liberalisation has a levitated income-redistributive effect with the magnitude of the de jure measure (KAOPEN) higher than that of the de facto measure (FDI); that exports, trade and “freedom to trade” have an equality incidence on income distribution; and that institutional and/or political liberalisation has a negative impact and; economic freedom has a negative income-redistributive effect, possibly because of the weight of its legal component.

In general, this study provides a variegated picture, findings tend to suggest that overall the reforms have increased income inequality in African countries. It would be risky to prescribe a general policy because of the diversity of the country. However, African countries’ better performance can be attributed to a combination of policies. For example avoiding the Marco price mixture of real exchange rate appreciation and high domestic interest rates; having capital controls and prudential financial regulations which would enable them to contain the negative consequence of capital flows; putting a system in place to direct export between African countries and encouraging sub regional integration agreement. The government should put in place countervailing social policies in order to withstand social coherence and smooth the adverse transition of liberalisation policies.

Three main elements of originality clearly standout: first, the estimation approach used in the paper considers both short- and long-run effects of in empirical strategy; second, an exhaustive plethora of liberalisation policies (trade, financial, political and institutional are considered); and third, recent data are used to appraise second generation reforms for more updated policy implications.

The purpose of this paper is to examine the effects of foreign trade liberalization and trade reforms on the process of structural upgrading, and explore the extent to which they provide impetus for exports.

This paper accounts for trade liberalization dates, cumulative years in open regime, and the density of 1,006 products in the patterns of comparative advantage for 132 countries from 1975 to 2000. The effects of trade liberalizations and trade reforms in open regime on future export performance are estimated by using various empirical strategies.

This paper finds that the speed of moving from simple poor-country goods to rich-country goods in export depends not only on having a route to nearby goods of increasingly higher value, but also on the increase in the cumulative years in open regime. In particular, a 1 percent change in the relatedness across products with trade reform in open regime increases the probability of exporting a new product by 2.0 percent more.

A contribution of this paper is that it measures the extent to which trade reform in open regime affects the evolution of comparative advantage, even after taking account of the role of relatedness of exported products as in the Hausmann and Klinger (2006, 2007). In this paper, empirical findings of a comprehensive product level cross-country time-series data analysis may contribute to generalize the role of trade reform on structural upgrading not only for a pro-competitive export country like Korea but also for a typical developing country.

The purpose of this paper is to examine the impact of multilateral trade policy (MTP) liberalization on developing countries’ economic exposure to shocks.

The analysis is conducted on a panel data set comprising 120 countries over the period 1996–2013 and uses the within fixed effects estimator.

The empirical results suggest that over the entire sample as well as sub-samples of least developed countries (LDCs) and non-LDCs, multilateral trade liberalization have a negative and significant impact on economic exposure to shocks. Interestingly, LDCs appear to experience the highest magnitude of the reducing impact of multilateral trade liberalization on countries’ economic exposure to shocks.

These findings suggest that a greater cooperation among countries in the world, including among WTO members to further liberalize trade would surely contribute to reducing developing countries’ economic exposure to shocks.

The current study shows that the current backlash against trade and the consequent strong appeal for domestic trade protectionist measures would likely to undermine the likelihood of further multilateral trade liberalization. One implication of this could be a rise in countries’ economic exposure to shocks.

To the best of the author’s knowledge, this is first the study on this matter.

This paper aims to empirically and theoretically study the role of domestic savings behind the financial stability and growth effects of different financial liberalizations, when the government is not able to commit to enforce financial contracts. The following liberalizations are considered. Macro financial liberalizations target capital flow and interest rate liberalization, whereas micro financial liberalizations target competition in the financial sector. Simultaneous liberalizations target both micro and macro dimensions.

This study theoretically solves a new simple model of different types of financial liberalizations, micro, macro and simultaneous. The focus is on the crisis and growth effects of countries liberalizing only macro dimensions of financial policy, relative to both micro and macro dimensions together, and on how the level of savings determines these effects. The study empirically uses data on macro and micro financial liberalizations for 91 countries between 1973 and 2005 to provide a taxonomy of liberalization strategies, and empirically tests whether domestic savings are related to the success of different strategies. Capital accumulation, investment profile and the frequency of financial crises are also evaluated.

The findings show that, empirically, simultaneous liberalizations are associated with larger growth only if the savings rate is large. If the savings rate is low, growth is larger when liberalizations target macro dimensions. Capital accumulation increases more with macro liberalizations under low savings and simultaneous liberalizations with high savings. Simultaneous liberalizations with low savings increase risks related to contract viability and expropriation, profits repatriation and payment delays. Simultaneous liberalizations with high savings are associated with smaller probabilities of financial crises. These observations are consistent with the theoretical model, where reduced competition in the financial sector can improve financial stability and reduce financial crises when savings are low.

The contribution of this paper, relative to the vast literature on financial liberalizations, is to document how savings determine the crisis and growth effects of macro and micro liberalizations. It provides and tests empirically a new channel for the role of savings when governments cannot commit to enforce financial contracts. This is informative for policymakers and policy institutions facing different strategies of financial liberalizations.

Recent studies of the impact of financial liberalization in emerging markets have not examined the dynamic impact of the liberalization process on equity returns despite the important implications on ongoing reform policies. We analyze six Asian equity markets using a dynamic adjustment model with three independent variables: market capitalization value, pricebook value ratio, and price‐earnings ratio. We use panel data for the period 1991‐2000 and the LSDVR (least square dummy variable regression) approach to identify the timing effects of liberalization. The stability of the model is also tested. The results indicate, in most cases, the significance of all three variables and the timing effects. Evidence of significant structural changes is also supported.

This paper aims to empirically reexamine the dynamic changes in emerging market volatility around stock market liberalization.

First, a bivariate GARCH‐M model which counts for partial market integration is developed for modeling stock market volatility in emerging market countries. Second, the Bai and Perron stability test in a linear framework and a pooled time‐series cross‐section model were employed to examine the empirical relationship between stock market liberalization and volatility.

Structural breaks detected in emerging market volatility series did not take place at the time of official liberalization dates, but they rather coincide with alternative events of liberalization process. The effects of official liberalization on return volatility are on average insignificant. The stock return volatility is however lowered when the participation of the US investors becomes effective and important on emerging markets, and when emerging markets increase in size.

The study assumes a static degree of market integration. Future research should extend our model by using a time‐varying measure of market integration.

Policymakers in frontier markets should open up local stock markets to attract foreign investments and to allow local firms to benefit from international risk sharing. Also, the gradual embankment of market‐liberalization is necessary to gain investors' confidence and to prevent the harmful effects of foreign capital flows.

The consideration of alternative events of liberalization process and the use of a powerful stability test to examine the time‐series properties of conditional volatilities.
