The purpose of this paper is to investigate regional impact of macroeconomic and regional policy impulses, using our newly developed multi-regional computable general equilibrium (CGE) model for three, structurally distinctive Polish macro-regions.

In this study, we build an interregional social accounting matrix for Poland and use it to develop a small scale, three-region CGE model, reflecting the size of regional economies and cross-regional differences in industrial structures, while also explicitly accounting for the dynamics of main economic relationships across regions, such as interregional flows in commodities, labor and capital. The model is subsequently use to simulate regional effects of various policy impulses.

We demonstrate important cross-regional differences in the transmission mechanism of macro-level policies, which either affect regional output and its individual components (as in the case of imposing shocks to VAT or PIT rates) or are limited to the components, while preserving a rather uniform impact on output (as in the case of imposing shocks to wages). Furthermore, we contribute to the regional policy equity-efficiency trade-off debate, by illustrating quantitatively how, due to structural differences, spatially targeted expenditure measures might promote either regional convergence or aggregate output growth at the country-level.

Prior to our study, regional CGE models have not been used to simulate spatial distribution of aggregate shocks in Poland or in any other CEE country. Another originality of our study lies in comprehensive evaluation of various policy impulses, from the perspective of their impact on the respective region, spillovers to the other regions and its overall, country-level effect.

Known as the major capital providers in Belt and Road countries and the largest carbon emitter in the world, what role China's outward direct investment (ODI) plays in carbon neutralization has become a matter of concern. This study aims to measure the impact of China's ODI on the carbon emissions of Belt and Road countries.

Based on an econometric model and an inter-regional input–output model, a new model measuring the carbon emission effects of ODI is developed.

The empirical results show that (1) in general, China's ODI generates an emission-reduction effect in Belt and Road countries; (2) The relationship between the emission-reduction effect and income level of host countries shows an approximate inverted U-shaped trend; and (3) China's ODI generates stronger emission-reduction effects on capital-intensive industries.

This study quantitatively measures the scale of carbon emission-increase and reduction effect, which is relatively lacking in previous studies. This study explores the heterogeneity from the perspectives of regions, countries and industries. The authors have compiled an inter-regional input–output table for the Belt and Road countries for 2014 to provide a broad basis for the study of related issues.

The purpose of this paper is to investigate how trade liberalization influences rural poverty reduction in China.

The authors make use of China Family Panel Studies survey data, take annual income of farmers of RMB2,300 and RMB3,450 as the poverty lines (poverty line 1 and poverty line 2, respectively). Residents below poverty line 1 and poverty line 2 are 2,580 and 2,661, respectively. Probit model is used to estimate the impact of trade liberalization on the poverty probability. Income-deciding equation is used to estimate the impact of trade liberalization on the income level of poor residents in rural areas. Income-deciding equation is also used to examine the transmission mechanism of trade liberalization affecting rural poverty.

This study finds that trade liberalization can reduce the poverty probability of rural residents and promote the income growth of poor residents in rural areas. Trade liberalization increases the income of poor residents and reduces poverty through transmission mechanisms such as promoting economic growth and financial expenditure.

To the authors’ knowledge, this is the first empirical study to quantitatively model the impact of trade liberalization on rural poverty reduction in China using residents’ survey data.

The first purpose of this study is to examine the impacts of climate-caused cereal productivity changes on food security, welfare and GDP in South Asian countries. The second purpose is to assess the agricultural subsidies and South Asia Free Trade Agreement (SAFTA) as policy responses to climate change.

The present study uses the computable general equilibrium (CGE) framework and econometric approach in an integrated manner to examine the economic impacts of climate-caused cereal productivity changes in South Asian countries. An econometric model is used to identify the impact of climate change on cereal yields and CGE approach is used to assess the future effect of climate change through simulations. In this course, the econometric findings are applied to Multiregional Global Trade Analysis Project 10 and then the model is calibrated for future projection.

The results indicate that there is a decrease in cereals production because of climate change and eventually it increases the prices of cereals, decreases the local consumption and GDP and, as a result, causes a loss in welfare. Subsidies and SAFTA have been found to have no substantial impact on increasing food security in South Asia.

The present study uses the concept of food demand for all cereals in an integrated way and focuses on the fiscal and trade policy responses to climate change.

A process of economic growth can certainly take place with insufficient diminution of poverty and with widening gaps in income distribution. In Ceara, as in many other states in Brazil and in the world, there are problems of poverty and of inequality, besides macroeconomic growth. Although measurement and definition questions may lead to different evaluations of its volume, it is clear that rural poverty is greater than urban poverty in Ceara, and much more than the urban poverty in the Metropolitan Region of Fortaleza. This picture is typical of most states in the process of economic development, and cannot be dismissed as a result of any specific conditions in this state.

The scope of this work is to explore whether Regional Comprehensive Economic Partnership (RCEP) would be beneficial to Bangladesh, given Bangladesh's strong ties with India and the west.

Using extended gravity equation and data from Head and Mayer (2021) and the Direction of Trade Statistic (IMF, 2021) for Bangladesh with its applicable partner countries from 1972 till 2019, the authors attempted to examine the potential impact of joining RCEP while keeping its relationship with South Asian Association for Regional Cooperation (SAARC), and other existing economic integration schemes intact.

Using traditional pooled ordinary least squares, two-stage least square and generalized method of moment techniques, it has been revealed that conventional partners in the South led by India are still beneficial to Bangladeshs trading line. Joining RCEP provides ample avenues for trade expansion without replacing the positive effects of SAARC.

Traditional partners from European, American and South Asian trading opportunities are still paying enough dividends to Bangladesh. RCEP is providing a trade-enhancing chance for Bangladesh in the eastern direction. This paper provides a policy suggestion to look east policy of government. A total overhaul of her tax structure through minimizing excessive reliance on import tariff revenue is desired to facilitate her to join RCEP in the future because most of its prospective RCEP partners are import partners.

This is the first and the only study which explores the feasibility of Bangladesh to join the RCEP by using the most recently updated gravity data in a panel framework.

1. Since its inception on November 15, 2020, Regional Comprehensive Economic Partnership (RCEP) has emerged as one of the largest economic integration areas in the world.

2. As a borderline country between South Asia and RCEP, Bangladesh is in a fix to take a decision either to join or not to join RCEP if they are invited.

3. This paper used the gravity equation in an extended form by taking Bangladesh with its 197 trading partners’ trade data for 1972–2019.

4. The findings postulate that the existing relationship with SAARC countries is still beneficial to its welfare, and RCEP is also economically helpful in enhancing its trade.

The aim of this paper is to deal with the linkage between agricultural trade liberalization and food security in Sub‐Saharan Africa.

The analysis uses the GTAP model which is a global dynamic applied general equilibrium model to assess how the multifarious trade and support policies in agriculture affect the poor in the Sub‐Saharan African group based on food security concerns. The policy strategies analyzed are two liberalization scenarios based on the proposals made in the present round of agricultural negotiations in terms of market access and export competition, plus a free agricultural trade benchmark scenario.

The results of alternative trade liberalization strategies on key food security indicators in the SSA region are ambiguous. The impact varies depending on the extent of liberalization and also the comparative advantage of the SSA group at the sectoral level.

Despite several studies on food security, especially after the food crisis in 2008, very little research has focussed on the agricultural trade liberalization impact with a CGE approach.
