Direct governmental production in agriculture in Ghana: Consequences for food production and consumption, 1960–1966 and 1967–1975

The article examines the effects of direct government production in agriculture in Ghana, both during the period 1962–1966 when it was a high agricultural priority, and during 1967–1975 when the government tried to withdraw. The article concludes that direct government production was a constraint on overall domestic food production in both time periods, although there may have been other social benefits resulting from the policies.     

Improving levels of service through enhanced distribution techniques at Newark Beth Israel Medical Center

In an effort to reduce cost and improve service, Materiels Management Distribution Services, in cooperation with a prime vendor, created a distribution method unique to the needs of Newark Beth Israel Medical Center. The project combined the vendor's expertise and ability to "deliver direct" to an internal hospital location by product group with the distribution staff's ability to complete the process and deliver the merchandise to the final destination in an expedited manner. This article provides a contract template that can be adapted for other collaborative efforts and highlights the components of a successful program: electronic data interchange, verification of usage and par, reconfiguration of space, direct pallet delivery, and some basic indicators of success.     

The performance effects of human resource managers' and other middle managers' involvement in strategy making under different business-level strategies: the case in Hong Kong

We first developed theory arguing that HR managers' and other middle managers' involvement during strategy making would have different effects on performance for firms pursuing different business-level strategies. Then, our empirical study tested the hypotheses in the context of HR managers and middle managers in the Hong Kong Special Administrative Region, People's Republic of China. We found that HR manager involvement during strategy making was positively related to perceptions of future business performance. The use of a differentiation strategy was also positively associated with future performance. Neither the use of a cost leadership strategy, however, nor involvement by other middle-level managers, was directly related to perceived future performance. Interestingly, pursuit of a cost leadership strategy, combined with either high HR manager involvement or high middle manager involvement, produced high business performance. Thus, we found a positive and significant interaction such that increasing levels of manager involvement in strategy and a cost leadership strategy was associated with much higher levels of performance. Lower levels of manager involvement combined with the cost leadership strategy, however, were related to much lower performance. No such interaction effect was apparent for differentiation strategies.     

Environmental Tax Reform and Government Expenditure

In a simple model of production with an imported polluting resource and involuntary unemployment we consider the effects of energy taxes, holding the real wage constant, under differing levels of government expenditure and externalities. Simulations reveal conflict between the goals of net welfare, employment and profitability over much of the relevant parameter range, thus extending the usual discussion of multiple dividends. However, potential net welfare and employment gains are substantial for plausible parameters. The optimal energy tax declines as government expenditure rises and is less than the Pigovian tax for plausible externalities.     

Computable general equilibrium with financial markets

Summary. There are a wide variety of theoretical general equilibrium models with incomplete security markets. In this paper we give a general recipe for using homotopy algorithm to compute equilibria in these models. In many models, taxes, transaction-costs or other market frictions introduce the additional difficulty that equilibrium prices or choices (but not equilibrium allocations) may be undetermined. In order to demonstrate how these difficulties can be dealt with, we develop a globally convergent algorithm to compute equilibria in a model with cash-in-advance constraints, several goods and incomplete financial markets. Furthermore we describe how to implement the algorithm using a publicly available suite of subroutines for homotopy-pathfollowing. Received: October 1, 1999; revised version: December 16, 2000     

Controlled and uncontrolled communication stimuli and organic food purchases: The mediating role of perceived communication clarity,perceived health benefits,and trust

Despite a growing demand worldwide, organic food remains a niche category, with consumers only purchasing it some of the time. This study examines the mediating effects of consumers’ perceived clarity of organic food-related communication, trust for, and perceived health benefits of organic foods in the relationship between controlled and uncontrolled communication stimuli and organic food purchases. We test our hypotheses on a sample of 1011 Australian organic food consumers using Structural Equation Modeling. We find that all mediators except perceived communication clarity perform as hypothesized, with the latter not mediating the relationship between uncontrolled communications and perceived health benefits of organic foods. The results suggest that marketers should ensure clarity in controlled organic food communications, signal health benefits of organic food and build consumer trust to generate organic purchases.

IT Governance and Types of IT Decision Makers in German Hospitals

Growing expenses for health care services in hospitals stress the potential of a well applied IT governance for cost reduction, productivity gains and a possible source for competitive advantages. The underlying explorative study analyzes the current status of IT governance through a survey among 206 IT decision makers in German hospitals. The quantitative analyses show that the most important requirements of IT managers for IT are the optimization and standardization of processes, that IT investments shift from administrative to medical IT applications, and that private hospitals display relatively higher IT budgets than do non-profit or public hospitals based on financial turnover. Further, two types of future IT decision makers are empirically identified. The types differ regarding their future role as initiators for process optimization and regarding the degree of involvement in strategic decision making.     

Fiscal Incidence in Ghana

We use methods developed by the Commitment to Equity Institute to assess the effects of government taxation, social spending and indirect subsidies on poverty and inequality in Ghana. We also simulate several policy reforms to assess their distributional consequences. Results show that, although the country has some very progressive taxes and well‐targeted expenditures, the extent of fiscal redistribution is small, but about what one would expect given Ghana's income level and relatively low initial inequality. Results for poverty reduction are less encouraging: were it not for the in‐kind benefits from health and education spending, the overall effect of government spending and taxation would actually increase poverty in Ghana. Eliminating energy subsidies and at the same time reallocating part of the savings to well‐targeted transfer programs could lower the fiscal deficit while reducing inequality and protecting the poor.
