Botswana's Macroeconomic Management of Its Mineral-Based Growth: It Used Mining Revenues for Development and Services but Must Now Broaden the Beneficiaries

Abstract . The economic performance and the political history of Botswana during 1974-84 contrasted significantly with the experience of virtually every other African country. The South African republic, immediately north of the Republic of South Africa, achieved steady real economic growth with improved social services and provision for its people's basic needs. This was achieved in spite of world recession and drought because its mineral wealth Was reserved for the people and mining companies had to pay for the privilege of extracting that wealth through a tax program limited to appropriating its surplus, while assuring the investors and entrepreneurs an adequate long-term return on capital and enterprise. But sound macroeconomic policies failed to provide even reasonably equitable benefits for the majority of the people. Sound micropolicies are needed to widen access to employment and earned income and to asset accumulation.     

Measuring Socioeconomic Effects When Using Income as Quality of Life Indicator

Abstract . By generalizing Stigler and Becker's idea of maintaining the “capital stock intact,” and incorporating it with other contributions to welfare economic analysis, this paper presents a modified conceptual framework for measuring and adjusting impacts of socioeconomic and environmental factors when income or consumption expenditure is used solely as a quality of life indicator. Such measurements and adjustments are made for differences in public needs and in the process of satisfying these needs. Application of this conceptual framework is illustrated, using statistics on police protection and crime rates.     

Assessment of Interjudge Reliability in the Open-Ended Questions Coding Process

In the process of coding open-ended questions, the evaluation of interjudge reliability is a critical issue. In this paper, using real data, the behavior of three coefficients of reliability among coders, Cohen’s K, Krippendorff’s α and Perreault and Leigh’s I _r are patterned, in terms of the number of judges involved and the categories of answer defined. The outcome underlines the importance of both variables in the valuations of interjudge reliability, as well as the higher adequacy of Perreault and Leigh’s I _r and Krippendorff’s α for marketing and opinion research.     

Henry George's Theory of State's Agenda: The Origins of His Ideas on Economic Policy in Adam Smith's Moral Theory

Abstract . The tension between Henry George's reformism and his laissezfaire liberalism was resolved through a system of natural liberty George derived from the relation between Adam Smith's ethics and economics. Crucial for George's nonutilitarian philosophy of government was the interdependence between the moral sense (sympathy) and the prevailing socioeconomic order. In the appropriate institutional environment, the role of the government was diminished since the pervasive moral sense insured justice by monitoring the individual's pursuit of economic self-interest. In contrast, a defective socio economic order required government intervention. For example, land monopoly and the maldistribution of income undermined the role of sympathy, promoted excessive self interest and the breakdown of the system of natural liberty. Government action through the single tax eliminated the “fear of want,” restored an operative moral sense and guaranteed justice in society. Under these conditions, government can provide additional services for a growing society without being susceptible to “corrupt and tyrannous” behavior.     

Henry George and His Philosophy: He Sought Equality of Opportunity to Use the Earth's Resources as Well as the End of Land Monopoly

Abstract . The George scholars today appear to be interesting the academic community in re-evaluating Henry George and his ideas. George, the 19th century American economist and social philosopher, dedicated himself to ending poverty by giving everyone equal access to the earth and its resources. He believed that land monopoly could be ended by taking the economic rent of all land and natural resources to meet the costs of government in lieu of taxes on labor and capital. George's writings revived interest in the ethos of the early settlers a time when sight was being lost of Pioneer America's contribution to the world's march toward freedom.     

Political Unionism and the Collective Objective in Economies of British Colonial Origin: The Cases of Jamaica and Trinidad

Abstract . Developing countries face an inconsistency between the need for more equitable distribution of income and wealth between classes and groups and the goals of an industrial relations system in which the trade unions have a systematic commitment to allied political parties to support them in exchange for some control over economic and social policy, or where unions compete with parties for popular support of certain social and political goals. This is designated as 'political unionism' in contradistinction to 'business unionism' where unions support any party whose overall strategy and objectives are most compatible. The analysis shows that ‘political unionism’ led, in Jamaica and in Trinidad and Tabago, to lags in growth which make industrial relations reform a necessity of an effective program of social change.     

Multivariate L1 mean

The center of a univariate data set {x ₁,…,x _n} can be defined as the point μ that minimizes the norm of the vector of distances y′=(|x ₁−μ|,…,|x _n−μ|). As the median and the mean are the minimizers of respectively the L ₁- and the L ₂-norm of y, they are two alternatives to describe the center of a univariate data set. The center μ of a multivariate data set {x ₁,…,x _n} can also be defined as minimizer of the norm of a vector of distances. In multivariate situations however, there are several kinds of distances. In this note, we consider the vector of L ₁-distances y′₁=(∥x ₁- μ∥₁,…,∥x _n- μ∥₁) and the vector of L ₂-distances y′₂=(∥x ₁- μ∥₂,…,∥x _n-μ∥₂). We define the L ₁-median and the L ₁-mean as the minimizers of respectively the L ₁- and the L ₂-norm of y ₁; and then the L ₂-median and the L ₂-mean as the minimizers of respectively the L ₁- and the L ₂-norm of y ₂. In doing so, we obtain four alternatives to describe the center of a multivariate data set. While three of them have been already investigated in the statistical literature, the L ₁-mean appears to be a new concept. Received January 1999     

Exact local Whittle estimation of fractionally cointegrated systems

Semiparametric estimation of a bivariate fractionally cointegrated system is considered. We propose a two-step procedure that accommodates both (asymptotically) stationary (δ<1/2)$(\delta <1/2)$ and nonstationary (δ≥1/2)$(\delta \ge 1/2)$ stochastic trend and/or equilibrium error. A tapered version of the local Whittle estimator of Robinson (2008) is used as the first-stage estimator, and the second-stage estimator employs the exact local Whittle approach of Shimotsu and Phillips (2005). The consistency and asymptotic distribution of the two-step estimator are derived. The estimator of the memory parameters has the same Gaussian asymptotic distribution in both the stationary and the nonstationary case. The convergence rate and the asymptotic distribution of the estimator of the cointegrating vector are affected by the difference between the memory parameters. Further, the estimator has a Gaussian asymptotic distribution when the difference between the memory parameters is less than 1/2.     

Improved stein-rule estimator for regression problems

Stein-Rule estimator for regression problems has been studied by several authors including Sclove (1968) and others listed in Vinod's (1978) survey. Ullah and Ullah (1978) provide the expressions for the mean squared error (MSE) of a double k-class (KK) estimator with parameters k₁ and k₂. When k₂=1 the Stein-Rule estimator becomes a special case of KK and an optimal choice of k₁ is known. This paper explores optimal theoretical choice of k₁ and k₂. We note that negative choices of k₂ are permissible, and that thereis a large range of choices for K₁ and k₂ where the MSE of the Stein-Rule estimator can be reduced for regression problems based on multicollinear data. A simulation experiment is included.     

Feedback orientation: A meta-analysis

Feedback orientation reflects an individual difference in one's receptivity to feedback. We present the results of a meta-analysis of the feedback orientation literature. Based on k = 46 independent samples, representing n = 12,478 workers, meta-analytic results suggest that feedback orientation is positively related to learning goal orientation (r_c = 0.39), job satisfaction (r_c = 0.33), work performance (r_c = 0.35), and feedback seeking (r_c = 0.43). Meta-analytic regression and dominance analysis was used to tease apart how related informal feedback constructs (i.e., feedback seeking, feedback environment, & feedback orientation) aid in the prediction of outcomes, above and beyond two established predictors of job attitudes and work performance: role clarity and leader-member exchange. We also present an interactive exploratory data analysis tool to aid in developing future research questions regarding the connection between informal feedback constructs and work outcomes.     

Biases,variances and covariances of raking ratio estimators for marginal and cell totals and averages of observed characteristics

Summary On the basis of a simple random sample from a population, on which a cross-classification is defined with known marginal frequenciesN _i. andN _.j , one wishes to estimate the cell frequenciesN _ij , as well as cell totalsY _ij , marginal totalsY _i. andY _.j , and the grand totalY for characteristics measured on the units. Various authors have discussed so-called raking ratio estimators, which are built up from the estimated cell values by addition. They have given the bias and variance of this estimator ofY. This paper derives biases, variances and covariances for the corresponding estimators of the cell and marginal totals and of the corresponding marginal averages.     

Some Determinants of Property Crime: Economic Factors Influence Criminal Behavior But Cannot Completely Explain the Syndrome

Abstract . An empirical analysis of the property crimes, robbery, burglary and larceny, is presented for all 120 counties in Kentucky. While this analysis is based on an economic model of crime, certain sociological and legal variables are included as well in the system of equations. Overall, the empirical results support prior studies’findings with the exception that a quadratic relationship is found to exist between urbanization and each of the property crimes. Furthermore, neither the economic nor the non economic influences measured appear more important for affecting crime rates. Specifically, results indicate that the level of poverty, the degree of tourism, the presence of police, the unemployment rate and the apprehension rate all affect property crimes. In contrast, the length of sentence, the degree of industrialization, the level of public assistance payments and the proportion of youth in the county have no affect on property crime rates in these areas.     

Irrational Expectations, Unclearing Markets and a Business Cycle That Won't Go Away: The Recent School of New Classical Economists Comes a Cropper on Basic Economic Facts

Abstract . The assumptions and conclusions of New Classical Macroeconomics (NCM) are critically examined. NCM grew out of the alleged failure of the Keynesian school to deal with the problems of stagflation of the 1970s. The two fundamental ideas of the NCM are the rational expectations hypothesis and the theory of instantaneous market clearing. According to the NCM, fiscal and monetary policies will achieve desired results if they are unanticipated. Business cycles are thought to be results of imperfect information on the part of rational agents (people). The NCM has been severely criticized by such prominent economists as Arrow, Tobin and Thurow.     

A conditional distribution approach to uniform sampling on spheres and balls in Lp spaces

Liang and Ng (Metrika 68:83–98, 2008) proposed a componentwise conditional distribution method for L _p -uniform sampling on L _p -norm n-spheres. On the basis of properties of a special family of L _p -norm spherical distributions we suggest a wide class of algorithms for sampling uniformly distributed points on n-spheres and n-balls in L _p spaces, generalizing the approach of Harman and Lacko (J Multivar Anal 101:2297–2304, 2010), and including the method of Liang and Ng as a special case. We also present results of a numerical study proving that the choice of the best algorithm from the class significantly depends on the value of p.     

The impact of public regulation on housing quality and on structural changes

This paper represents a theoretical investigation of profit maximizing behavior of a landlord under rent control. The situation envisioned is one that the landlord owns, free and clear, either two housing units ready to merge or one large one ready to convert into two small ones; in each case the units are already in place, such that capital costs are sunk and treated as bygones. Each unit has a technology of production of housing services with a fixed input of quantity of space (shelter) and a variable input of quality, that is affected by physical ageing (non-controllable) and by maintenance (controllable). At starting time t₀, we have a state of quality and a historical state of initial quality Q?_i, at the time the building was built, with the implicit constraint that Q_i(t) < Q?_i, for all t> t₀. The analysis addresses the general question of housing structural changes—conversion or merger—and how these changes are being accelerated under the threat of rent control.     

Ready or Not? Homosexuality,Unit Cohesion,and Military Readiness

The U.S. military argues that homosexuals are unfit for service because their presence compromises military readiness and unit cohesion. Based on this assumption, it continues to discharge homosexuals at an average rate of approximately 925 per year. On the other hand, the extant research suggests that homosexuals are no more disruptive to military life than their heterosexual counterparts. By integrating the legal and scientific literature, this paper examines the soundness of the military’s assumptions and aims to improve our understanding of the issues involved. Within this context, the efficacy of the military’s “Don’t Ask, Don’t Tell, Don’t Pursue” policy and whether it is in the best interest of the military and its soldiers and sailors is discussed.

Forecasting contemporal aggregates of multiple time series

The paper considers forecasting a contemporal linear aggregate y_t of a vector time series Z^'_t =(Z_1t,...,Z_kt). We first disciss the case where Z_t follows a stationary multiple moving average process and propose a measure of the efficiency of aggregation. A necessary and sufficient condition is given for the case of no gain by employing the component series. Extension of the results to stationary multiple autoregressive process and some non-stationarity processes is discussed, and an illustrative example is given.     

Core and competitive equilibria of a coalitional exchange economy with infinite time horizon

The core and competitive equilibria of a large exchange economy on the commodity space ?^∞${?}^{\infty }$ will be discussed. We define the economy as a measure on the space of consumers’ characteristics following Hart and Kohlberg (1974), and prove the existence of competitive equilibria and their equivalence with the core without assuming the convexity of preferences.     

Henry George and Europe: As Dissident Economist and Path-breaking Philosopher, He was a Catalyst for British Social Reform

Abstract . Henry George's influence was greater in the United Kingdom than in the United States. The 80s and 90s there were particularly favorable for the reception of his revolutionary ideas. Though, thanks to such thinkers as Alfred Russell Wallace and James and John Stuart Mill, a land reform movement already existed, its sudden rise to national significance was due to George. George's writing and speaking skills and his dedication moved many serious citizens into the political Left and heavily influenced men and women who became leaders of British non-Marxian socialism, at the formation and consolidation of their movement. While George's followers broke with both the Wallace and socialist movements, George's rhetorical talents awakened the broad circles of thinking people to a consciousness of the full range of the social question.
