A Political Economy Approach to the Neoclassical Gradualist Model of Transition

Abstract.  A political economy approach to the neoclassical gradualist model of transition requires the exposition of what I define the primary elements of the model, which are economic analysis, definition of a good society, speed, political structure, ideological structure and whether the initial conditions were incorporated in the model. After the identification of the primary elements of the neoclassical gradualist model the next step is to identify secondary elements, the desired changes with respect to price liberalization-stabilization, privatization, institutional structure, monetary policy and the financial system, fiscal policy, international trade and foreign aid and social policy. The analytical framework developed makes possible to understand the neoclassical gradualist model from a new and more enlightening perspective. We are better able to comprehend the complexities involved and the disagreements about the reform process. The adoption of a gradual process of transition did not only involve specifying the required policies of a successful transition but also entailed a process, a sequence by which the reforms should be introduced. As such, a process of transition consistent with the policies recommended by the neoclassical gradualists economists is developed. The conclusion reveals the inconsistencies in the model.     

Multidimensional generalized Gini indices

Summary. The axioms that characterize the generalized Gini social evaluation orderings for one-dimensional distributions are extended to the multidimensional attributes case. A social evaluation ordering is shown to have a two-stage aggregation representation if these axioms and a separability assumption are satisfied. In the first stage, the distributions of each attribute are aggregated using generalized Gini social evaluation functions. The functional form of the second-stage aggregator depends on the number of attributes and on which version of a comonotonic additivity axiom is used. The implications of these results for the corresponding multidimensional indices of relative and absolute inequality are also considered.Received: 20 August 2003, Revised: 26 May 2004, JEL Classification Numbers: D63.

Population Ageing and Social Expenditure in New Zealand

As the population ages there will be potentially significant implications for a wide range of economic variables, including in particular the fiscal costs of social expenditures. Long‐term fiscal planning requires estimates of the possible future path of public spending. This article presents projections for 14 categories of social spending. These projections are based on detailed demographic estimates covering fertility, migration and mortality. Distributional parameters are incorporated for all of the major variables, and are used to build up probabilistic projections for social expenditure as a share of gross domestic product using simulation. Attention is focused on health expenditures which are disaggregated into seven broad classes. In addition, we explore the impacts of alternative hypotheses about future health costs. While it can be predicted with some confidence that overall social expenditures will rise, the results suggest that long‐term planning would be enriched by recognising the distributions around point estimates of projected social costs.     

Inter‐state dynamics of invention activities, 1930–2000

We study the dynamics of the cross‐section distribution of patents per capita for the 48 continental US states from 1930 to 2000 using a discrete‐state Markov chain. We test for and find evidence in favor of the (knowledge) convergence hypothesis. The distribution of patents is converging to a limiting distribution that is significantly more concentrated than its initial distribution. States in the extreme are more mobile than states in the middle of the cross‐sectional distribution and are likely to move to the middle. However, the rate of convergence to the limiting distribution is ‘slow’. Copyright © 2006 John Wiley & Sons, Ltd.     

The U.S. current account deficit and the expected share of world output

We investigate the possibility that the large current account deficits of the U.S. are the outcome of optimizing behavior. We develop a simple long-run world equilibrium model in which the current account is determined by the expected discounted present value of its future share of world GDP relative to its current share of world GDP. The model suggests that under some reasonable assumptions about future U.S. GDP growth relative to the rest of the advanced countries—more modest than the growth over the past 20 years—the current account deficit is near optimal levels. We then explore the implications for the real exchange rate. Under some plausible assumptions, the model implies little change in the real exchange rate over the adjustment path, though the conclusion is sensitive to assumptions about tastes and technology. Then we turn to empirical evidence. A test of current account sustainability suggests that the U.S. is not keeping on a long-run sustainable path. A direct test of our model finds that the dynamics of the U.S. current account—the increasing deficits over the past decade—are difficult to explain under a particular statistical model (Markov-switching) of expectations of future U.S. growth. But, if we use survey data on forecasted GDP growth in the G-7, our very simple model appears to explain the evolution of the U.S. current account remarkably well. We conclude that expectations of robust performance of the U.S. economy relative to the rest of the advanced countries is a contender—though not the only legitimate contender—for explaining the U.S. current account deficit.     

China＇s Economy in 2005： At a New Turning Point and Need to Fix Its Development Problems

I. High Growth, Higher Stakes China’s economy in 2005 experienced another year of surging growth, with its total GDP(based on recent revision) expanding at 9.9 percent to reach 18.23 tn yuan (US$2.26 tn).1 Growth in 2005 was slightly lower than the 10.1 percent in 2004; but it was nonetheless very high. Sustained high growth is accompanied by potential high risks, and it inevitably raises the issue of future sustainability of high growth. Although the Chinese economic policy-makers in 200…     

Nuclear Power

Nuclear power has never been free from the stifling involvement of government. Heavy regulation has reduced the ability of entrepreneurs to develop and provide new means for the generation of energy using nuclear fuel. The strict parameters dictated by government officials are based upon outdated technology, an improper regulatory philosophy, and preclude innovation in nuclear power generation. Anti-market environmentalists misunderstand the implications of a free market in nuclear power and argue against it based on problems that are actually caused by government involvement. Our position is neither for nor against nuclear power. We advocate a hands-off policy where the nuclear industry is left to its own devices, free from governmental regulations and subsidies: free to succeed or fail on its own. Thus, our position is neither right-wing conservative (removing regulations), nor left-wing liberal (removing subsidies). Very much to the contrary of both positions, we propose a free-market in nuclear power.
