Employment and Growth Effects of Tax Reforms AgEcon
Michaelis, Jochen; Birk, Angela.
This paper explores how revenue-neutral tax reforms impact employment and economic growth in a model of endogenous growth and search frictions on the labor market. We analyze how savings and the incentive to create new jobs are affected by tax swaps between wage income taxes, payroll taxes, capital income taxes and taxes levied on capital costs. In our framework, the payroll tax is found to be neutral. If this tax is used to finance a cut in the capital income tax, we will observe an increase in both growth and, via the capitalization effect, employment. Most other tax reforms, however, imply a trade-off between employment and growth.

Nuclear versus Coal plus CCS: A Comparison of Two Competitive Base-load Climate Control Options AgEcon
Tavoni, Massimo; van der Zwaan, Bob.
In this paper we analyze the relative importance and mutual behavior of two competing base-load electricity generation options that each are capable of contributing significantly to the abatement of global CO2 emissions: nuclear energy and coal-based power production complemented with CO2 capture and storage (CCS). We also investigate how, in scenarios from an integrated assessment model that simulates the economics of a climate-constrained world, the prospects for nuclear energy would change if exogenous limitations on the spread of nuclear technology were relaxed. Using the climate change economics model WITCH we find that until 2050 the resulting growth rates of nuclear electricity generation capacity become comparable to historical rates observed...

Leadership Cycles AgEcon
Denicolo, Vincenzo; Zanchettin, Piercarlo.
We study a quality-ladder model of endogenous growth that produces stochastic leadership cycles. Over a cycle, industry leaders can innovate several successive times in the same industry, gradually increasing the magnitude of their technological lead before being replaced by a new entrant. Initially, new leaders are eager to enlarge their lead and do much of the research, but if they innovate repeatedly, their propensity to invest in R&D decreases. Eventually they stop doing research altogether, and as they are overtaken a new cycle starts. The model generates a skewed firm size distribution and a deviation from Gibrat’s law that accord with the empirical evidence. We also consider various policy measures, showing that in some cases policy should...

Impact of Cultural Tourism upon Urban Economies: An Econometric Exercise AgEcon
Bellini, Elena; Gasparino, Ugo; del Corpo, Barbara; Malizia, William.
In recent years, interest in tourism has spread rapidly throughout many small and medium European cities, which previously have not necessarily considered themselves as tourist destinations. Tourism is increasingly seen as a potential lever towards high economic growth, measured both in terms of income and employment. In the present Working Paper we report the analysis on the economic impact undertaken in the framework of the PICTURE Project, showing the results of a novel econometric exercise to statistically assess the impacts of cultural tourism upon European municipalities. More precisely the analysis aims at estimating the effects of tourism specialisation on local income and prices. The Working Paper is built as follows. Section 1 presents and...

10 years of transition in Ukraine agriculture: An analysis of productivity and efficiency of enterprises AgEcon
Lissitsa, Alexej; Odening, Martin; Babycheva, Tamara.
This paper analyzes efficiency and total factor productivity (TFP) change of large agricultural enterprises during their transition to a market economy in Ukraine. In this case the efficiency is calculated by data envelopment analysis and the productivity change is measured by the Malmquist Productivity Change Index in the period between 1990 and 1999. On average, TFP declined by 6% annually, dropping a total 42%. The main reason for the observed TFP decline is a decrease in technical efficiency, which is found to be remarkably significant. At the same time there is a high variation among individual enterprises: their distribution of efficiency scores widens, which indicates that the farms diverge with respect to their economic performance. The Tobit...

INTERNATIONAL SPILLOVERS, PRODUCTIVITY GROWTH AND OPENNESS IN THAILAND: AN INTERTEMPORAL GENERAL EQUILIBRIUM ANALYSIS AgEcon
Diao, Xinshen; Rattso, Jorn; Stokke, Hildegunn Ekroll.
Thailand has experienced economic growth well above world averages for about 40 years. It is a challenge to understand the sources of this high growth path, and in particular why growth has not slowed down with assumed decreasing returns to capital. We develop an intertemporal general equilibrium model separating between agriculture and industry, and with open capital market and endogenous productivity growth to analyze the underlying adjustment mechanisms. Foreign technology spillover embodied in trade is assumed to be the driving force of the productivity growth, consistent with econometric evidence. The high growth experience is understood as a transition path with interaction between productivity growth, openness and capital investment. Counterfactual...

SOURCES OF GROWTH AND SUPPLY RESPONSE: A CROSS-COMMODITY ANALYSIS OF CHINA'S GRAIN SECTOR AgEcon
Colby, Hunter; Diao, Xinshen; Somwaru, Agapi.
A growth accounting method is used to analyze the sources of growth in China's rice, wheat, corn and soybeans, the four most important crops in China's grain sector, during 1978-97. A large TFP contribution to growth in grain production is found in the period immediately following China's rural economic reform (1978-85). In recent years the growth rate of TFP falls sharply, contributing less than 20 percent of growth in grain production, as increased use of inputs became the major engine of growth. If the current government policy environment remains unchanged, China's grain production will become increasingly costly and constrain future growth and competitiveness in world grain markets. The supply response of the four grains is estimated using a...

CAP Reforms and Total Factor Productivity Growth in Belgian Agriculture: A Malmquist Index Approach AgEcon
Coelli, Tim J.; Perelman, Sergio; Van Lierde, Dirk.
Have the 1992 and 2000 CAP reforms had any discernable effect upon agricultural productivity? In this study we derive detailed information on the total factor productivity (TFP) growth of arable farms in Belgium over a 16-year period from 1987 to 2002. Calculations are based on a carefully constructed high-quality detailed farm-level data set containing 1728 observations, involving over 100 farms in most years. Three output variables (cereals, other crops, other outputs) and four input variables (land, labour, capital and other inputs) are constructed, using multilateral Fisher index numbers where crop aggregation is required. The TFP measures are calculated using a Malmquist TFP index relative to a series of data envelopment analysis (DEA) frontiers....

GMOs: Prospects for Increased Crop Productivity in Developing Countries AgEcon
Evenson, Robert E..
Genetically Modified Crops (GMO foods) have been widely available to farmers since 1996. The Gene Revolution, based on recombinant DNA (rDNA) genetic engineering techniques, is seen by proponents as both supplanting Green Revolution varieties, based on conventional plant breeding techniques, and potentially enabling “disadvantaged” production environments, unreached by Green Revolution varieties to achieve productivity improvements. This paper argues that the private firms supplying GM crop products have generally had little interest in selling products in disadvantaged production environments. The paper also argues that present rDNA techniques allow only static gains from specific “trait” improvements. But these GM products can be installed on Green...

GROWTH THEORY AND ACCOUNTING FOR GROWTH OF THE TAIWANESE ECONOMY AgEcon
Lin, Pei-Chien; Roe, Terry L..
A growth accounting and an econometric exercise are used to provide insights into the evolution of the Taiwanese economy over the period 1966-96. The approach links the GDP function of a multiple sector neoclassical growth model to growth accounting and, subsequently to the estimation of the parameters of this function. The growth accounting results show that the contribution of total factor productivity (TFP) to growth in GDP averaged about 32 percent over the period, and this contribution increased as the economy approached its long-run equilibrium during the decade of the 1980s, with evidence of some departure during 1991-96. Growth in TFP increased output growth in industry and services while growth in skilled labor benefited all sectors. Growth in...

The Historical Fertility Transition: A Guide for Economists AgEcon
Guinnane, Timothy W..
The historical fertility transition is the process by which much of Europe and North America went from high to low fertility in the nineteenth and early twentieth centuries. This transformation is central to recent accounts of long-run economic growth. Prior to the transition, women bore as many as eight children each, and the elasticity of fertility with respect to incomes was positive. Today, many women have no children at all, and the elasticity of fertility with respect to incomes is zero or even negative. This paper discusses the large literature on the historical fertility transition, focusing on what we do and do not know about the process. I stress some possible misunderstandings of the demographic literature, and discuss an agenda for future work.

An Evolutionary Edge of Knowing Less (or: On the "Curse" of Global Information) AgEcon
Stark, Oded; Behrens, Doris A..
Consider a population of farmers who live around a lake. Each farmer engages in trade with his two adjacent neighbors. The trade is governed by a prisoner’s dilemma “rule of engagement.” A farmer’s payoff is the sum of the payoffs from the two prisoner’s dilemma games played with his two neighbors. When a farmer dies, his son takes over. The son decides whether to cooperate or defect by considering the actions taken and the payoffs received by the most prosperous members of the group comprising his own father and a set of his father’s neighbors. The size of this set, which can vary, is termed the “span of information.” It is shown that a larger span of information can be detrimental to the stable coexistence of cooperation and defection, and that in...

Regional and Sector Environmental Efficiency Empirical Evidence from Structural Shift-share Analysis of NAMEA data AgEcon
Mazzanti, Massimiliano; Montini, Anna.
This paper provides new empirical evidence on regional–national disparities in environmental efficiency, based on case studies of Italy and the Lazio region, which includes the city of Rome. Shift-share analyses provide evidence on the drivers of environmental efficiency and on sector specificity. This confirms the usefulness of this method for studying the environmental economics realm, in order to investigate structural and efficiency factors at the level of within country environmental efficiency performance, even in light of the different shares of services. Our evidence shows that although the Rome region has achieved higher environmental performance compared to Italy mainly thanks to its being less industry based, some critical points in the energy...

Stark, Oded; Behrens, Doris A..
Consider a population of farmers who live around a lake. Each farmer engages in trade with his m adjacent neighbors, where m is termed the "span of interaction." Trade is governed by a prisoner’s dilemma "rule of engagement." A farmer’s payoff is the sum of the payoffs from the m prisoner’s dilemma games played with his m/2 neighbors to the left, and with his m/2 neighbors to the right. When a farmer dies, his son takes over. The son who adheres to his father’s span of interaction decides whether to cooperate or defect by considering the actions taken and the payoffs received by the most prosperous member of the group comprising his father and his father’s m trading partners. Under a conventional structure of payoffs, it is shown that a large span of...
