Climate policy vs. agricultural productivity shocks in a dynamic computable general equilibrium (CGE) modeling framework: The case of a developing economy

The main objective of this paper is to compare the cost of climate policy consistent with the 2 °C global warming target (Paris Agreement target) with the cost of climate change induced agricultural productivity shocks, using a recursive dynamic CGE model for India. The social cost of carbon, in terms of loss in agriculture sector, is estimated to be about 2 percent of GDP, at zero rate of discount, under conservative forecasts of fall in agricultural productivity. In comparison, the cost of climate policy consistent with the Paris Agreement target of 2 °C is about 1 percent of GDP. Thus, there is a strong case for the adoption of ambitious climate policy in India, provided other countries also adhere to the same. Besides, revenues generated from the carbon tax and emission allowance could be a means to support the development and adoption of new energy and agricultural technologies, to increase social sector expenditure and to reduce abatement costs.     

Monetary and fiscal policies' effect on agricultural growth: GMM estimation and simulation analysis

The concept of sustainable economic growth is closely linked with the agricultural growth. This is especially true in the context of under-developed countries. Pakistan is a typical under-developed country that has huge labor force employed in conventional rural economy and more than half of the population relies on agriculture for subsistence. The study examines the agricultural growth through developing a model using the data from agricultural sector of Pakistan for the period 1972–2010. The model is primarily based on input–output reduced form structural equations approach. It is then estimated by GMM, validated and used for deterministic simulation analyses. Finally the validated model is used to critically analyze the impact of fiscal, monetary and energy policies on the agricultural output. We conluded that recent fiscal and monetary policies should be continued, while the energy policy needs to be modified in order to improve the agricultural GDP and reduce the rural poverty situation in the country.     

An analysis of irrigated agricultural outcomes under the prior appropriation doctrine: hypotheses and applications

This article measures irrigated agricultural outcomes under the prior appropriation doctrine by developing a model of farmers’ land allocations in response to water supply change. The modelling approach considers the institutional factors of water rights and permits the inclusive determination of water and land allocations. We utilize farm-level data of irrigated agriculture in Water District #1 in Idaho to examine the predictions from our theoretical model. The water rights priority date is consolidated at the farm level and used to differentiate farmers’ responses. We test a set of hypotheses that relate to water supply and crop revenue. Our results suggest that the water rights priority has a profound impact on agricultural outcomes, indicating strong institutional effects and weak influence of market-based approaches. Farmers respond to both long-term and seasonal water supply change and variation, and they respond to seasonal water supply forecasts in varied ways depending on their water rights portfolios, thus signalling a disproportionate distribution of potential impacts of water supply change.     

Trade Liberalization in Agriculture in Developed Nations and Incidence of Child Labour in a Developing Economy

This paper is an attempt to analyse the consequence of trade liberalization in agriculture in the developed countries on the incidence of child labour in a developing economy in terms of a three‐sector general equilibrium model with informal sectors. Adult labour and child labour are substitutes for each other in the two informal sectors of the economy and are used together apart from capital in producing two exportable commodities. The interesting result that appears from the analysis is that agricultural trade liberalization in the developed countries may be effective in bringing down the incidence of child labour in the system. The paper substantiates the desirability of trade liberalization in agriculture in the developed nations from the perspective of the developing economies for reasons other than welfare improvement.     

Agricultural subsidy policies fail to deal with child labour under agricultural dualism: What could be the alternative policies?

We provide a theoretical explanation why agricultural subsidy policies are likely to fail to ensure simultaneous eradication of the incidence of child labour and improvement in the well-being of the poor working families in terms of a three-sector general equilibrium model with child labour and agricultural dualism. We identify both demand and supply side effects of any policy intervention on child labour. We also suggest two alternative policies, a scheme of direct cash transfer to poor people and economic growth through foreign direct investment (FDI), both of which would be effective in achieving these twin objectives of a welfare government.     

Agricultural enlargement of the EU under Agenda 2000: Surplus of farm labour versus surplus of farm products

In the Commission's proposals for reform of the Common Agricultural Policy (CAP) and enlargement of the EU (Agenda 2000), the agriculture of Central and Eastern Europe (CEE) is denied future access to compensatory payments for cuts in support prices in the EU15. To offset this, the acceding countries are promised a similar net amount of structural aid for their economy and society at large. This dual treatment aims at preventing agricultural surpluses and intersectoral distortion after accession. However, the actual situation and dynamics of agriculture in Central Europe (CE) compared to that in the EU does not support the surplus assumption globally, but only for certain products, chiefly grains. So far overlooked, but nevertheless, a key obstacle opposing competitive recovery, is the tendency of the dual, post-communist agrarian structures, faced with high rural unemployment, to protect long-term underproductive farm labour to the detriment of capital and land remuneration, mainly in livestock production. This configuration is supported by specific trade and land protections, and loose qualittative regulations that will be challenged by the EU enlargement. So, after accession under the Agenda 2000 schedule, it seems likely that CEE countries will achieve European competitiveness only at the cost of some recession, further deterioration of trade balances with the EU 15 and sharp decreases in farm employment levels. These factors would chiefly affect livestock production which, combined with crop intensification, is likely to result in a substantial increase in grain surpluses. Later on, the enlarged EU will have to bear the inevitable social consequences that transitional periods after accession might otherwise have postponed.     

The transformation of the agricultural population and the urbanisation process in China

"Nine causes for the occurrence of surplus agricultural labour with the modernisation of agriculture have been identified. Several solutions to this problem are presented. Urbanisation of the agricultural population in a way suited to China's characteristics is necessary, important and possible." An example of labor saving through mechanization in Heilongjiang province is presented.     

FDI in agricultural land, welfare and unemployment in a developing economy

The paper purports to examine the consequences of foreign direct investment (FDI) in agricultural land in a developing economy using a three-sector general equilibrium model with simultaneous existence of unemployment of both skilled and unskilled labour. The analysis finds that FDI in agriculture does not only improve national welfare unequivocally but also mitigates the unemployment problem of both types of labour. The paper theoretically justifies the desirability of flow of FDI in agriculture in the developing economies.     

THE BEHAVIOR OF U.S. PUBLIC DEBT AND DEFICITS DURING THE GLOBAL FINANCIAL CRISIS

In this paper we test the sustainability of U.S. public debt for the period 1916–2012 by analyzing how the primary surplus to gross domestic product (GDP) responds to changes in the debt to GDP ratio in a time‐varying parameter model. Further, we determine the stationarity property of the debt/GDP ratio while accommodating possible breaks in the data caused by wars and economic crisis under both the null and alternative hypotheses of an endogenous unit root test. The results show that the U.S. public debt was sustainable until 2005 when the primary surplus to GDP reacted negatively to the debt/income ratio. This is further exacerbated during the global financial crisis when primary surpluses continued to fall with increased debt, thus jeopardizing the sustainability of fiscal policy. While the stationarity test shows that the U.S. fiscal debt/GDP ratio is sustainable, it fails to highlight the risk that its debt policy has been becoming unsustainable in recent years.

Climate change and economic growth: An intertemporal general equilibrium analysis for Egypt

This study advances the state of the art in country-level computable general equilibrium analysis for climate change impact and adaptation analysis by incorporating forward-looking expectations. The analytic framework is used to explore the long-run growth prospects for Egypt in a changing climate. Based on a review of existing estimates of climate change impacts on agricultural productivity, labour productivity and the potential losses due to sea-level rise for the country, the model is used to simulate the effects of climate change on aggregate consumption, investment and income up to 2050. Available cost estimates for adaptation investments are employed to explore adaptation strategies.The simulation analysis suggests that in the absence of policy-led adaptation investments, real GDP towards the middle of the century will be 6.5% lower than in a hypothetical baseline without climate change. A combination of adaptation measures, that include coastal protection investments for vulnerable sections along the low-lying Nile delta, support for changes in crop management practices and investments to raise irrigation efficiency, could reduce the GDP loss in 2050 to around 2.6%.Further work along these lines for developing countries in climate change hotspot regions deserves a high priority on the research agenda in economic modelling.

Productivity,Structural Change and Latin American Development

We calibrate a simple neoclassical growth model adapted to illustrate a process of structural transformation or industrialization to a group of nine South American countries. The paper shows that low levels of agricultural productivity can substantially delay the process of industrialization, which, together with low levels of non‐agricultural productivity observed in recent decades, satisfactorily explains the significant differences in gross domestic product (GDP) per capita levels among the countries in our sample. The results suggest that Argentina underwent the process of industrialization first followed by Uruguay, Chile, Brazil, Colombia, Ecuador, Peru, Paraguay and Bolivia. The model predicts that the ranking of these countries in terms of GDP per capita would follow this order until convergence occurs. The empirical evidence confirms the prediction of the model with the exceptions of Uruguay and Chile which caught up with Argentina in terms of GDP per capita levels in the late 1980s.     

Economic management and organization of Hungarian agriculture

The performance of Hungarian agriculture demonstrates that socialist agriculture in Hungary is able to satisfy the entire food demand of the population and even produce a considerable surplus. An overview of the major characteristics of the Hungarian agricultural system is given. Its performance is analyzed in an international comparison; then its enterprise structure is discussed. The major part of the article deals with the economic management system of Hungarian agriculture and includes a discussion of the main features of present-day agricultural policy and its price and tax system.     

Forecasting output gaps in the G-7 countries: the role of correlated innovations and structural breaks

Trend GDP and output gaps play an important role in fiscal and monetary policy formulation, often including the need for forecasts. In this article, we focus on forecasting trend GDP and output gaps with Beveridge-Nelson trend-cycle decompositions trend-cycle decompositions and investigate how these are affected by assumptions concerning correlated innovations and structural breaks. We evaluate expanding window, one-step-ahead forecasts indirectly for the G-7 countries on the basis of real GDP growth rate forecasts. We find that correlated innovations affect real GDP growth rate forecasts positively, while allowing for structural breaks works for some countries but not for all. In the face of uncertainty, the evidence supports that in making forecasts of trends and output gap policy-makers should focus on allowing for the correlation of shocks as an order of priority higher than unknown structural breaks.     

Determinants of labour productivity: Comparison between developing and developed countries of Asia‐Pacific

The current study investigates the trends in labour productivity of the major developing and developed economies of the Asia‐Pacific region and examines its determinants over the period 1980–2014. The study analyses capital deepening, human capital, technology, share of agriculture in GDP, financial development, institutional quality, inflation as well as macroeconomic variables as potential determinants of productivity, and identifies the differences in the impact of these factors on the productivity of developing and developed countries. Using panel cointegration and group‐mean fully modified ordinary least squares estimation, the study finds that capital deepening, human capital, technology, institutional quality and macroeconomic variables (i.e. government size and openness) are significant determinants of labour productivity of both developing and developed economies of the Asia‐Pacific region. The study further finds that while both trade openness and foreign direct investment affect productivity of developing economies positively, only trade openness has a positive and significant impact on the productivity of developed economies. The share of agriculture in GDP affects the labour productivity of developing Asia‐Pacific economies significantly but not that of developed economies. Furthermore, capital deepening has a much higher impact on the productivity of developing Asia‐Pacific economies than that of developed economies.

农业多功能性与国际农产品贸易政策改革--兼论我国世贸谈判的应对策略

农业除了生产食物和纤维以外,还在经济、社会和环境等方面具有非商品功能。农业多功能性问题日益受到各国关注。全球经济一体化形势下国际农产品贸易政策改革进程中,对农业多功能问题的争辩体现了农产品进口国与出口国的利益之争。作为一个发展中农业大国,农业经营规模超小型等特点决定了我国在WTO框架下的农产品国际贸易中处于不利地位,因此我国应顺应世界农业功能多元化的潮流,在强调农业食物功能的同时,充分利用“绿箱政策”进行农业生产能力建设,积极发展功能多元化可持续农业。     

Foreign Direct Investment, inequality, and growth

This paper examines the interactions between Foreign Direct Investment (FDI), inequality, and growth, both from an empirical and a theoretical point of view. Using a panel of 119 developing countries, we observe that FDI promotes both inequality and growth, and tends to reduce the share of agriculture to GDP in the recipient country. We then set up a growth model of a dual economy in which the traditional (agricultural) sector uses a diminishing returns technology, while FDI is the engine of growth in the modern (industrial) sector. The main predictions of the model are consistent with the stylized facts observed in the data.     

Labour markets, liquidity, and monetary policy regimes

Abstract.  We develop an equilibrium model of the monetary policy transmission mechanism that highlights information frictions in the market for money and search frictions in the labour market. The information friction increases the persistence in the response of interest rates following monetary policy regime shifts. This occurs because agents have incomplete information about the nature of the shifts and optimally update their inflation forecasts using an 'adaptive' expectations rule. The search friction transmits the interest rate movements to the labour market by affecting job creation activities; together, the two frictions imply that unemployment reacts very gradually to monetary policy shocks.
