Integrated water and economic modelling of the impacts of water market instruments on the South African economy

A static computable general equilibrium model of South Africa is adapted to compare new taxes on water demand by two industries, namely forestry, and irrigated field crops. Comparisons are made with respect to both the short and the long run, in terms of three target variables, namely (i) the environment; (ii) the economy; and (iii) equity. Since the taxes on the two industries do not raise the same amount of revenue, the target variables are calculated per unit of real government revenue raised by the new taxes (also referred to as the marginal excess burdens of the taxes). The model results are robust for moderate values of the water elasticity of demand in the two industries, in both the long and the short run. The tax on irrigated field crops performs better in terms of all three the target variables in the short run. In the long run the tax on irrigated filed crops is better in terms of water saving, but reduces real GDP and the consumption by poor households.     

Simulated economic impacts in applied trade modelling: A comparison of tariff aggregation approaches

This paper assesses the performance of two recently developed tariff aggregators in reducing tariff aggregation bias by analysing Swiss beef market liberalisation scenarios. Specific relevant sources of bias are addressed: substitution effects on import demand, Tariff Rate Quotas and overprotection in tariffs. The aggregators are linked to a global large-scale partial equilibrium model and benchmarked against a standard aggregator. The choice of the aggregation method shows considerable effects on simulated economic impacts, specifically if the dispersion in tariffs or tariff cuts is large. A large bias is revealed in simulated gains from trade liberalisation using the standard aggregator. The impacts on traded quantities are found to be overestimated, while price and welfare effects can be higher or lower by switching to alternative aggregation methods. By reducing aggregation bias and depicting negotiated tariff schedules more directly, the proposed aggregators enhance the contribution of trade modelling to evidence-based policy making.     

Countries, regions and trade: On the welfare impacts of economic integration

We study the impact of falling international trade costs and falling national transport costs on the economic geography of countries involved in an integration process. Each country is formed by two regions between which labor is mobile, whereas there is no international mobility. Goods can be traded both nationally and internationally at positive, but different, costs. A decrease in trade costs and/or in transport costs has a direct impact on prices and wages, which allows us to account for the impact of changes in these parameters on the economic geography and welfare of each country. We show that, as trade barriers fall, the benefits of integration come after its costs. We also show that national transport policies are of the beggar-thy-neighbor type. On both counts, policy coordination is required in the process of economic integration.     

An interdisciplinary model of soybean yield in the Amazon Basin: The climatic, edaphic, and economic determinants

Soybean production is one of the main economic forces driving the expansion of the agricultural frontier in the Brazilian Amazon. To assess the potential for expansion we estimate a model of soybean yield that integrates the major climatic, edaphic, and economic determinants in the Amazon Basin. Yield is modeled as a function of yield as simulated by a crop physiology model that captures the effects of climate and physical attributes on the development of soybean plant; fertilizer applications; and economic/spatial parameters such as credit, transports costs and latitude. Current values of these determinants indicate that roughly 20% of Amazon Region or ∼ 1,000,000 km² (excluding protected areas) can generate yields greater than 2000 kg/ha. Soybean production may be possible over a wider area of Amazon, but realizing this potential requires improvements in economic determinants such as the transportation infrastructure.     

Assessing the impact of the 2004 Olympic Games on the Greek economy: A small macroeconometric model

This paper examines the impact of the Athens 2004 Olympic Games on the Greek economy. Using a small aggregate macroeconometric model we find evidence to support the view that the Olympics is an event that could successfully boost the economy of the host city by generating benefits that outweigh the preparation cost. Consistent with recent literature in this area, whilst the impact effects are quite strong during the preparation phase and the year the Games took place, the long-term economic legacy effects appear to be quite modest.     

Human capital and measurable dynamic gains from economic integration: An application to the economic integration of North and South America

The paper looks at the source of dynamic gains to trade liberalization using a two-country model with both physical and human capital accumulation. The model is calibrated and used to examine the effect of the economic integration of Canada and the United States with Latin America. The analysis assumes that differences in productivity levels between regions are due entirely to differences in human and physical capital endowments. Key assumptions are that capital is internationally mobile and human capital formation is income constrained. The simulated impact of moving to a hemispheric free trade area is significant. The long-run impacts are also different from the short-run efficiency effect predicted by conventional static triangle-rectangle analysis. The long-runmultiplier effect on static output gains are on the order of 2.0 to 2.5 for the South—that is long-run output gains are 2.0 to 2.5 times predicted short-run static gains. In the case of the North, static predictions of gain are ambiguous in sign over the longer run; in some cases there are small dynamic gains-in others. small losses. Investment diversion toward Latin America is a prominent characteristic of the results.     

Against the Wind: Labor Force Participation of Women and Economic Instability in Iran

In the last three decades, Iranian women's educational attainment has continuously increased while their fertility rate has fallen rapidly. Yet in spite of these developments, which in many countries have a positive effect on women's labor force participation, female labor force participation (FLFP) rates have remained at low levels. This paper argues that despite its overall static trend, FLFP of some Iranian women responded to economic pressures induced by macroeconomic instabilities. Looking at the Iranian economic crisis of 1994–5, the study shows that, controlling for individual fixed effects, married women in rural areas and never-married women in urban areas increased their participation rate by as much as 38 percent. No change in hours worked was found for any group of women. The differences in responses and their underlying reasons have policy implications for many developing countries.     

A new definition and framework for the development of a national technology strategy: The case of nanotechnology for Iran

In this research, we use the concepts of “national technology policy” as well as the “firm technology strategy” in defining a new definition for “national technology strategy”. Then, by examining several national technology strategies in a variety of fields in different countries the national nanotechnology strategy for Iran is developed. Furthermore, using capability-effectiveness matrix and SWOT analysis we identify strategies of nanotechnology development in Iran. Finally, considering other countries' strategies and the results of PROMETHEE Method, we prioritize different areas of nanotechnology for Iranian economy, and test for the validity of the extracted strategies.     

Distinguishing characteristics of the Martiniquan economy and constraints on modelling

The decentralization law confers on local elected representatives powers in the fields of economic, social and cultural development. For this purpose we have constructed a large-scale macroeconometric model for Martinique. The purpose of this article is to present the model and discuss its capacity. To begin with we shall set out its general structure. We shall then describe the relationships that have been selected for solving the model. Finally we shall examine the power of the model, first of all in retrospective simulations and then from the point of view of economic policy. The variants selected are: a demand policy, a supply policy and a policy aimed at bringing the Martiniquan minimum wage up to the level of the metropolitan wage.     

The political economy of corruption and the role of economic opportunities1

In many developing and transition countries, we observe rather high levels of corruption. We argue that the missing political support for anti‐corruption policies is due to a lack of economic and financial reforms. Our model is based on the fact that corrupt officials have to pay entry fees to get lucrative positions. In a probabilistic voting model, we show that this, together with the lack of economic opportunities, makes anti‐corruption policies less likely. Compared to a reformed economy, more voters are part of the corrupt system and, more importantly, rents from corruption are distributed differently. Economic liberalization increases the support for anti‐corruption measures. The additional effect of financial liberalization is ambiguous.     

The effects of economic and political integration on fiscal decentralization: evidence from OECD countries

Abstract .  This paper examines the impact of economic and political integration on the vertical government structure. It argues that, by increasing the market size and the benefits of decentralized provision of public goods, integration triggered the recent process of decentralization in OECD countries. A panel analysis relates the degree of fiscal decentralization to economic and European integration, controlling for interregional heterogeneity, economies of scale, and institutions. The results mostly support a decentralizing effect of economic integration in general and of European integration in particular for heterogeneous EU countries, whereas participation of subnational governments in national decision-making is associated with more centralization.     

The impacts of China on economic growth: Evidence for Brazil,Chile, and Peru

This study empirically analyzes the direct impacts derived from the swift increase in exports to China (referred to as “the impact of China”) on the economic growth of three selected South American countries, Brazil, Chile, and Peru, during the commodity boom between 2001 and 2008. The results stemming from the balance-of-payments-constrained growth model suggest that the magnitude of China’s impact was less than 1 percent, although it ranged from the largest to the second largest impact among all trading partners for the three countries. The estimated balance-of-payments growth rate of domestic income is lower than the real growth rate of domestic income. This is because the growth rates of the export volumes were not sufficient even during the commodity boom, on account of the continued increasing trends of income elasticity of demand for imports. Furthermore, the income elasticities of demand for imports from China were especially high. Therefore, the three countries will continue to face further increase in the income elasticity of demand for imports as well as a stagnant growth rate of export volumes. Thus, the balance-of-payments position will continue to be the main growth constraint for these countries.     

Nationalism, development and integration: the political economy of Ernest Gellner

In this paper, we show how in Gellner we can find a stimulatinganalysis of the institutional equilibria that characterise agrarianand industrial society and the conditions that make possibleinstitutional change from one equilibrium to another. This allowsa convincing account of the reasons why some countries industrialisedbefore others and why nationalism had such an uneven impacton the development of market economies. We consider the relationbetween Gellner's analysis and other theories of organisationand point out how Gellner can help to solve some paradoxes thatarise in these theories. We also argue that joining Gellner'scontribution to the analysis of the positional nature of statusand power reinforces his conclusion about the necessary stagnationof agrarian societies and the necessary (over)accumulation ofdifferent forms of capitalism. We conclude by examining theimplications of his analysis for the process of globalisationand its challenge to national states.     

The impact of third-country effects and economic integration on China's outward FDI

The study employs a spatial econometric model to explore the impact of third-country effects and economic integration on China's outward FDI (OFDI). The results show that the pattern of China's OFDI tends toward a complex FDI without third-country effects. The degree of economic integration and host country's political risk both have a negative influence on China's OFDI. Furthermore, greater cultural proximity between China and the host country, as well as greater per capita income (market size), both have significant benefits to China's OFDI. The host country's market opportunity has a significant negative effect on China's OFDI.     

The Third Way and the third sector: New Labour's economic policy and the social economy

This paper reviews the relationship between Labour's economicpolicy and the third sector. Since 1997, the third sector hasreceived significant government support and has gradually movedfrom the economic periphery towards the centre such that itis now instrumental in the delivery of a range of governmentpolicies. It operates alongside both the private and publicsectors in delivering employment, education, health and socialcare, housing and environmental policies. The impact of thishas been seen in measures of social exclusion, poverty, theenvironment, social capital, as well as GDP and employment.Future policies should strive to maintain and develop the distinctivecapabilities of third sector organisations and the balance betweeneconomic, social and environmental objectives.     

Reducing climate change impacts on agriculture: Global and regional effects of mitigation, 2000–2080

What are the implications for agriculture of mitigating greenhouse gas emissions? By when and by how much are impacts reduced? Where does it matter most? We investigated these questions within the new A2 emission scenario, recently developed at the International Institute of Applied Systems Analysis with revised population and gross domestic product projections. Coupling an agro-ecological model to a global food trade model, two distinct sets of climate simulations were analyzed: 1) A non-mitigated scenario, with atmospheric CO₂ concentrations over 800 ppm by 2100; and 2) A mitigation scenario, with CO₂ concentrations stabilized at 550 ppm by 2100. Impacts of climate change on crop yield were evaluated for the period 1990–2080, then used as input for economic analyses. Key trends were computed over the 21st century for food demand, production and trade, focusing on potential monetary (aggregate value added) and human (risk of hunger) impacts. The results from this study suggested that mitigation could positively impact agriculture. With mitigation, global costs of climate change, though relatively small in absolute amounts, were reduced by 75–100%; and the number of additional people at risk of malnutrition was reduced by 80–95%. Significant geographic and temporal differences were found. Regional effects often diverged from global net results, with some regions worse off under mitigation compared to the unmitigated case.     

General equilibrium modelling of the direct and indirect economic impacts of water quality improvements in the Netherlands at national and river basin scale

The main objective of the study presented in this paper is to estimate the direct and indirect economic impacts of water quality policy scenarios in the Netherlands focusing on the reduction of emission levels of nutrients and a number of eco-toxicological substances. For this purpose, an Applied General Equilibrium (AGE) model consisting of 27 production sectors is extended to water through the inclusion of substitution elasticities between labour, capital and emissions to water in the sectors' production functions. The macro-economic costs of a 10, 20 and 50% reduction of the emission levels in the year 2000 of ten priority substances in the EU Water Framework Directive vary between 0.2 and 9.4% of Net National Income (NNI). A large share of the total economic costs are borne by important sources of pollution like commercial shipping, the chemical and metal industry. However, important spin-off effects due to adaptation take place in the tertiary service sector. Besides the estimation of the economy-wide impacts of water quality improvements, the novelty of the study presented here is found in the downscaling of national and sector results to river basin level and the estimation of shadow prices for water-polluting substances through the introduction of an emission permits market.     

Corruption and corporate leverage in an emerging economy: The role of economic freedom

This study investigated the effects of corruption and economic freedom on corporate leverage. We also evaluated how economic freedom shapes the effect of corruption on corporate leverage. Using a sample of Vietnamese firms covering a nine-year period from 2010 to 2018, we find evidence that increased control of corruption has a significant positive impact on firm leverage, whereas the opposite is true for economic freedom. This effect is robust to alternative measures of control of corruption as well as advanced estimation methods, such as firm-fixed effects and quantile regressions. Our results also reveal that the positive impact of corruption controls on corporate leverage is more pronounced for firms with high economic freedom. Econometrically, our findings indicate that firms with better control over corruption prefer debt financing, as demonstrated by their higher leverage ratio.     

International stock markets comovements: the role of economic and financial integration

The contribution of economic and financial integration to international stock markets comovements are investigated by means of a large scale macroeconometric model, set in the factor vector autoregressive framework (F-VAR). The findings point to a relevant role for both economic and financial integration in explaining international stock markets comovements for the G-7 countries. While economic integration would exercise its effects through the common response of stock markets to global economic shocks, financial integration would operate through financial shocks spillovers, particularly at the regional level.
