Effects of Educational Expenditures on Regional Inequality in the Social Quality of Life

A bstract . Earlier studies by Liu on Quality of Life (QOL) indicators have pointed out the problems of concentration interregional inequality among the fifty states in U.S.A. Noting that the interregional inequality problem has been gradually alleviated over the past two decades, this paper attempts to provide some rudimentary explanations about this converging phenomenon through a labor market adjusting process towards social, economic and spatial equilibrium. Published state data and QOL indicators developed by Liu for 1960, 1970 and 1978 tend to support the hypothesis that investment in human resources , especially through improved elementary and secondary education , would enhance social mobility which would in turn improve labor and capital productivity. The reduced regional inequality in economic QOL seemed to be more a response than a cause when compared to that in social QOL, because variations in educational expenditures were found to be more significantly related to the social QOL indicators than to the economic ones.     

The relationship between carbon dioxide emissions and economic growth: quantile panel-type analysis

This paper samples the data of 138 countries during the 1971–2007 period, and performs an empirical test to validate the relationship between carbon dioxide emissions and economic growth. It first performs panel data analysis and quantile regression analysis to estimate the long-run elasticity relationships, and then analyzes the short-run error correction model to verify the causal relationship between the two. The empirical results indicate the following. (1) The long-run relationship between global carbon dioxide emissions and GDP is stable, with 32.6% of the sampled countries showing cross-coupling of the two (with an elasticity value of greater than 1), 47.1% reporting relative-decoupling (with an elasticity value between 0 and 1), and 20.3% seeing absolute-decoupling (with an elasticity value of smaller than 0). (2) The quantile regression shows that long-run elasticity declines along with the rise of carbon dioxide emission quantiles. In other words, cross-coupling turns into relative-decoupling. (3) The analysis of short-run panel data and quantile regressions mostly support the feedback relationship between carbon dioxide emissions growth and economic growth. This is consistent with the hypothesis developed by Kuznets. (4) According to the results of the quantile regression, the higher the quantiles, the faster and more stable of the short-run error-correction mechanism of the adjustments from short-run disequilibrium to long-run equilibrium. (5) Under the low-quantile carbon dioxide emissions growth and economic growth, the relationship between these two is not stable of the short-run disequilibrium adjustments in the error-correction adjustment process. However, the relationship between these two is steady and feedback in the case of high quantiles. Therefore, the first priority to combat global warming is to focus on the countries with high economic growth and high carbon dioxide emissions growth.     

Trade, migration and regional unemployment

A by now large literature in regional economics has greatly improved our understanding of the determinants of the observed spatial disparities in productivity. However, this literature neglects what seems to be a robust and persistent fact accompanying regional productivity differences: high productivity regions also have lower unemployment than low productivity regions. In this paper, we set out a model in the New Economic Geography (NEG)/job search tradition to explore the theoretical determinants of this fact. We find that the same forces producing regional agglomeration and productivity differences also generate persistent unemployment disparities. Moreover, we highlight a contrast between the short-run and long-run effects of migration on regional unemployment. In particular, migration from the periphery to the core may reduce unemployment disparities in the short-run, but exacerbates them in the long-run.     

Application of Quality of Life Indicators to Socioeconomic Problems:

Abstract . Liu has presented and applied to several categories of areas a method of estimating comparative values for measuring the quality of life. This method is analyzed and extended through an application permitting evaluation of social and economic policies for country towns in Australia. Issues in Liu's method, particularly relating to the procedure for standardizing measurements and a much-needed validation test, are examined and, it is hoped, resolved. The nature of Liu's results is compared with that of the Australian results and they are found to be similar, particularly in that the quality of life values were useful in explaining migration, and were even better in explaining certain components of migration. The study extended the method to analysis of policy choices.     

A long-run Pure Variance Common Features model for the common volatilities of the Dow Jones

In this paper, a new model to analyze the comovements in the volatilities of a portfolio is proposed. The Pure Variance Common Features model is a factor model for the conditional variances of a portfolio of assets, designed to isolate a small number of variance features that drive all assets’ volatilities. It decomposes the conditional variance into a short-run idiosyncratic component (a low-order ARCH process) and a long-run component (the variance factors). An empirical example provides evidence that models with very few variance features perform well in capturing the long-run common volatilities of the equity components of the Dow Jones.     

Exploring the link between research and economic growth: an empirical study of China and USA

In this paper, we explore the link between scientific and technical research and economic growth in China and USA over the sample period 1981–2012 using the extended Cobb–Douglas model with capital per worker and the quantity of scientific and technical journal articles (research publications) per worker. We examine the cointegration relationship and present the short-run and long-run results using the autoregressive distributed lag bounds procedure. Further, we examine the direction of causality between research publications per worker results and economic growth variables using the Toda and Yamamoto (J Econom 66(1–2):225–250, 1995) procedure. Our results indicate for both countries research publications per worker positively influence the output per worker both in the short-run and the long-run. The causality results for China indicate a bi-directional causality between research publications per worker and output per worker, duly emphasizing the mutually reinforcing effect. In case of USA, we note a unidirectional causation output per worker to research publications per worker indicating that output Granger cause research publications.     

Explanation for market response to seasoned equity offerings

In this paper, we use a multivariate framework to extend the recent univariate seasoned equity offering (SEO) research that investigated the valuation impact of inside ownership. Our multivariate findings re-enforce and add to the univariate findings as we show that the inside ownership level is a consistent factor in accounting for short-run and long-run returns around SEOs, while the decrease in inside ownership has no impact on short-run returns but influences long-run returns in a manner inconsistent with signaling theory. Compared to prior research, our regression tests do a much better job of accounting for returns associated with SEO announcements. For short-run regression tests, the four major factors associated with superior stock returns are: lower underpricing; greater profitability prior to SEO; lower inside ownership level; and, less stock price variability prior to SEO. For long-run regression tests, the four major conditions linked to superior returns are: greater profitability prior to SEO; smaller inside ownership level; relative size of the offering; and, greater decrease in inside ownership level.

Long-run (and short-run) effects of low-income government housing policies are examined, in a model that treats housing as a durable good which declines in quality over time. Short-run and long-run market equilibria are characterized, rent subsidies are analyzed in detail, and results for other policies are presented.     

The Influence of Geography on the Spatial Agglomeration of Production in the European Union

Abstract

Small regions and towns often experience problems such as high out-migration and unemployment. In these situations there is an urgent need to do something positive. Infrastructure development projects, partially financed by the national government, are a popular suggestion. We ponder the relevance of these actions in this paper in a context of project evaluation. We introduce computable general equilibrium (CGE) modelling as a complement of the other quantitative evaluation techniques. We will use the town of Lapua in South Ostrobothnia, Finland, which is planning to implement two large-scale infrastructure projects, as an example. Our simulation tool is the Finnish multi-sector and interregional CGE RegFin model. We consider the regional short-run effects of the construction phase, the long-run effects of new business activity and the so-called secondary effects based on the commuting and trade patterns of the households.     

Bank capital and the macroeconomy: Policy considerations

We develop a macroeconomic model in which the balance sheet condition of financial institutions plays an important role in the determination of asset prices and economic activity. The financial intermediaries in our model are required to make investment commitments before a complete resolution of idiosyncratic funding risk that can be addressed only by costly refinancing, forcing them to behave in a risk-averse manner. The model shows that the balance sheet condition of intermediaries can drive asset values away from their fundamentals, causing aggregate investment and output to respond to shocks to intermediaries. We use this model to evaluate several public policies designed to address balance sheet problems at financial institutions. With regard to short-run policies, we find that capital injections conditioned upon voluntary recapitalization can be a more effective tool than asset purchases. With regard to long-run policies, we demonstrate that higher capital requirements can have sizable short-run effects on economic activity, and that a long transition period helps avoid undesirable side effects. Finally, we show that the marginal effects of policies can be larger during “crises” because of the nonlinear interactions between some financial frictions and policy actions.     

The linkage between insurance activity and banking credit: Some evidence from dynamic analysis

This paper investigates the long-run and short-run linkages between insurance activity and banking credit for G-7 countries. To minimize the pretest bias and overcome the structural changes, we adopt the bootstrap Granger causality test applied to full sample and subsamples with a fixed window size. The Johansen cointegration test with GMM-IV estimator finds a long-run positive relation between the series. The full sample results of bootstrap Granger causality test show that there is predictive power from life insurance activity to banking credit only for France and Japan, while the short-run causal relationships between nonlife insurance activity and banking credit are country-specific. However, parameter stability test results suggest that the short-run results in full sample are unreliable. The results of rolling VAR models report that the causal linkages between them are time-varying across various subsamples. These findings offer some useful insights for achieving the co-evolution between insurance and banking credit markets.     

REGIONAL DEVELOPMENT IN CHINA: INTERREGIONAL TRANSPORTATION INFRASTRUCTURE AND REGIONAL COMPARATIVE ADVANTAGE

Significant economic disparities among China's Eastern, Central, and Western regions pose unequivocal challenges to social equality and political stability in the country. A major impediment to economic development, especially in the poor, remote Western region, is the shortage of a transportation infrastructure. The Chinese government has committed to substantial investment for improving the accessibility of this vast, land-locked region as a mechanism for promoting its development. The paper examines the impacts of the intended transportation infrastructure build-up on the Western region's comparative advantage and its interregional trade. The World Trade Model is extended to represent this investment and applied to determine interregional trade in China based on region-specific technologies, factor endowments and prices, and consumption patterns as well as the capacities and costs of carrying goods among regions using the interregional transportation infrastructure in place in the base year of 1997 and that planned for 2010 and 2020. The model is implemented for three regions, 27 sectors, and seven factors. The results indicate that the planned infrastructure build-up will be cost-effective, will increase benefits especially for the Western region, and that it can conserve energy overall at given levels of demand but substitute oil for coal. Based on these and other model results, some recommendations are offered about strategies for regional development in China.     

Adaptive learning and monetary exchange

This paper investigates three classic questions in monetary theory: How can an intrinsically worthless asset, such as fiat money, maintain value as a medium of exchange? What are the short-run and long-run effects of a change in the money supply? What is the social cost of inflation? I answer these questions using a microfounded model of monetary exchange that replaces the rational expectations assumption with an adaptive learning rule. First, I show that monetary exchange is a robust arrangement in the sense that agents are able to learn the stationary monetary equilibrium while the non-monetary equilibrium is unstable under learning. Second, an unanticipated monetary injection has real effects in the short-run because learning the value of money takes time. In the long run, agents successfully learn the value of money, hence money is neutral. Third, under a constant money growth policy, an increase in the growth rate of money increases output in the short-run producing a short-run Phillips curve. A ten percent increase in the money growth rate has a social cost of 0.41 percent of output per year. Alternatively, a ten percent decrease in the money growth rate has a social benefit of 0.37 percent of output per year.

Asset prices with non-permanent shocks to consumption

Most standard asset-pricing models assume that all shocks to consumption are permanent. We relax this assumption and allow also for non-permanent shocks. In our specification, the long-run mean of consumption growth is constant; consumption levels are subject to short-run deviations from their long-run trend. The implications of our model are dramatically different from those obtained in the prior literature. A canonical and parsimonious asset pricing model with CRRA preferences and non-permanent shocks can reproduce the equity premium, high return volatility and return predictability with a coefficient of relative risk aversion below ten. This finding suggests that non-permanent shocks can play an important role in explaining asset pricing puzzles.     

DEA evaluations of long- and short-run efficiencies of digital vs. physical product “dot com” companies

This paper applies Data Envelopment Analysis to determine relative efficiencies between internet dot com companies that produce only physical products and those that produce only digital products. To allow for the fact that the latter are relatively inexperienced, a distinction is made between long- and short-run efficiencies and inefficiencies, with a finding of no statistically significant difference in the short run but digital product companies are significantly more efficient in the long run. A new way of distinguishing between long- and short-run performances is utilized that avoids the need for identifying the time periods associated with long-run vs. short-run efficiencies and inefficiencies. In place of “time,” this paper utilizes differences in the “properties” that economic theory associates with long- and short-run performances.     

Tests on the validity of static equilibrium models

This paper provides a framework to test the validity of static cost minimizing equilibrium assumptions that form the basis for much of the empirical literature on industrial production. The point of departure in our model is to allow the observed technology to be at a short-run equilibrium where firms minimize variable costs while being constrained by the utilization levels of quasi-fixed factors. The long-run equilibrium is then inferred by minimizing total costs with the optimal adjustment of quasi-fixed factor levels.We use results from the optimization problem to form tests with respect to quantities and prices. In the quantity space version, departures between the actual and the optimal long-run levels of quasi-fixed factors are tested for statistical significance. A significant non-zero departure implies the rejection of a static equilibrium specification. In the price space version, the test is cast as a comparison of the market price and the long-run shadow value of a quasi-fixed factor. Although the two versions would give identical results in the non-stochastic case, the rejection powers of these two tests are found to depend on the particular functional form chosen to represent the production process (i.e. cost function).In an application based on aggregate U.S. manufacturing where capital is taken to be quasi-fixed, we were able to reject the static equilibrium specification. These results cast doubt on the validity of a number of previous empirical studies.     

GRANT EQUIVALENT EXPENDITURE ON INDUSTRIAL SUBSIDIES IN THE POST-WAR UNITED KINGDOM

ABSTRACT The paper constructs a consistent series for UK central government expenditure on industrial subsidies over the post-war period, valuing incentives in grant equivalent terms from the position of a firm undertaking investment appraisal. The analysis includes direct subsidy payments, as well as tax allowances, and provides a disaggregation between those subsidies available on a national, regional and sectoral or firm specific basis. A time-series analysis of the assembled data shows important differences between these components, with regional assistance performing a long-run distributive role, while other elements perform a stabilisation function. The short-run patterns are broadly constant across governments, but the long-run relationships exhibit structural breaks related to both political and economic events.     

Nonlinear minimization estimators in the presence of cointegrating relations

In this paper, we consider estimation of a long-run and a short-run parameter jointly in the presence of nonlinearities. The theory developed establishes limit behavior of minimization estimators of the long- and short-run parameters jointly. Typically, if the long-run parameter that is present in a cointegrating relationship is estimated, its estimator will be superconsistent. Therefore, we may conjecture that the joint minimization estimation of both parameters jointly will result in the same limit distribution for the short-run parameter as if the long-run parameter was known. However, we show that unless a regularity condition holds, this intuition is false in general. This regularity condition, that clearly holds in the standard linear case, is identical to the condition for validity of a two-step Granger–Engle type procedure. Also, it is shown that if the cointegrated variables are measured in deviation from their averages, the standard asymptotic normality result (that one would obtain if the long-run parameter was known) holds.
