Antecedents of the small firm effect: the role of knowledge spillover and blocked mobility for employee entrepreneurial intentions

Small firms are said to produce more entrepreneurs than larger ones (“small firm effect”). Applying existing theories, we analyze how different management positions influence employee entrepreneurship in small firms. Based on a panel study of 4832 cases, we provide evidence for the fact that small firms indeed produce more entrepreneurs. Moreover, we show that lower management positions of small firm employees are responsible for this small firm effect. We conclude that small firms seem to create an environment in which employees on low management positions strongly benefit from knowledge spillover effects as they are educated necessary skills, knowledge and expertise, and are able to build up networks conducive to entrepreneurship (“knowledge spillover effect”), while not having the multifaceted advancement opportunities as in large companies (“blocked mobility effect”).     

POVERTY COMPARISONS WITH ABSOLUTE POVERTY LINES ESTIMATED FROM SURVEY DATA

The objective of measuring poverty is usually to make comparisons over time or between two or more groups. Common statistical inference methods are used to determine whether an apparent difference in measured poverty is statistically significant. Studies of relative poverty have long recognized that when the poverty line is calculated from sample survey data, both the variance of the poverty line and the variance of the welfare metric contribute to the variance of the poverty estimate. In contrast, studies using absolute poverty lines have ignored the poverty line variance, even when the poverty lines are estimated from sample survey data. Including the poverty line variance could either reduce or increase the precision of poverty estimates, depending on the specific characteristics of the data. This paper presents a general procedure for estimating the standard error of poverty measures when the poverty line is estimated from survey data. Based on bootstrap methods, the approach can be used for a wide range of poverty measures and methods for estimating poverty lines. The method is applied to recent household survey data from Mozambique. When the sampling variance of the poverty line is taken into account, the estimated standard errors of Foster–Greer–Thorbecke and Watts poverty measures increase by 15–30 percent at the national level, with considerable variability at lower levels of aggregation.     

The J-Curve

If a country with a balance of payments problem, that is, insufficient foreign exchange receipts to meet foreign exchange requirements, seeks to remedy the situation by currency devaluation, things may get worse before they get better. This so-called J-curve effect occurs if the domestic-currency prices of exports are sticky, whether because they are cost based or subject to longer term contracts, so that export prices in foreign currency fall. Until favourable volume effects outweigh the unfavourable price effect, the balance of payments deteriorates. Such a J-curve effect should be distinguished both from the longer term erosion of the beneficial effects of devaluation as domestic costs and the prices of non-tradables rise and from the apparent J-curve due to the ‘valuation effect’. If the current account is in deficit before devaluation, as will usually be the case, devaluation will widen the deficit in domestic currency because domestic-currency imports rise by a larger amount than exports. This is a pure valuation effect, of no significance for external balance. But it is liable to lead to unduly pessimistic judgements about the effectiveness of devaluation. In Australia during 1985–86, the current account deficit increased by $A3.5 billion, despite substantial depreciation of the $A. The main reason was a sharp deterioration in the terms of trade which is estimated to have worsened the current account by $A4.25 billion. Most of this was exogenous, though J-curve effects may have made a contribution. In addition, the valuation effect contributed a further, illusory, widening of the deficit, valued in domestic currency, by over $A1 billion. To avoid misleading inferences from the valuation effect, it is suggested that the balance of payments should, if possible, be presented in foreign currency.     

THE CAUSAL LINK BETWEEN FINANCIAL INCENTIVES AND WEIGHT LOSS: AN EVIDENCE‐BASED SURVEY OF THE LITERATURE

Obesity and overweight are linked to diseases that cost society a significant amount of resources. While behavior modification can reduce the problem, instigating such lifestyle changes is an uneasy task. One potential way to reduce the problem is through the use of financial incentives. In this survey, we review the available evidence, properly emphasizing studies that credibly yield meaningful estimates of the effect of financial incentives on weight loss. We find that the scientific literature on the subject has not yet satisfactorily settled whether such a mechanism is effective at eliciting the desired behavioral and health outcomes. We therefore advocate a rigorous large‐scale randomized experiment to provide reliable estimates of the effect.     

Human resource management in relation to generic strategies: a comparison of chemical and food&drink companies in the Netherlands and Great Britain

In this paper, specific personnel policies and their relationship to generic strategies are examined in the light of the concept of human resource management (HRM). Since data from twelve Dutch and eight British companies in the food&drink and chemical industries reveal that the implementation of HRM components is subject to a societal effect–and thus HRM has a different meaning in Dutch companies than in their British counterparts–a typology of HRM at a more strategic level is proposed to facilitate the analysis of the relationship between HRM and generic strategies. Although in the majority of cases the HRM policy supports the generic strategy pursued, many problems and paradoxes remain in the analysis of an HRM–strategy fit.     

Globalization and economic development

A feature of the continuing integration of the world economy is the globalization of production and the consequent rise of trade in parts and components. Products are more internationalized and less identified with any particular country. Non-trivial shares of the value-added of many exports consist of imports and vice versa. Extension of the international division of labour beyond finished products offers developing countries a broader range of choices for industrialization. This paper explores the implications of these developments in the context of a standard trade model. Component specialization in a developing country's import sector is shown to be superior in overall welfare terms to specialization in the integrated product. Output and employment are higher in the sector, but the wage-rental ratio is lower.     

Higher fuel and food prices: impacts and responses for Mozambique

Rising world prices for fuel and food represent a negative terms‐of‐trade shock for Mozambique. The impacts of these price rises are analyzed using various approaches. Detailed price data show that the world price increases are being transmitted to domestic prices. Short‐run net benefit ratio analysis indicates that urban households and households in the southern region are more vulnerable to food price increases. Rural households, particularly in the North and Center, often benefit from being in a net seller position. Longer‐term analysis using a computable general equilibrium (CGE) model of Mozambique indicates that the fuel price shock dominates rising food prices from both macroeconomic and poverty perspectives. Again, negative impacts are larger in urban areas. The importance of agricultural production response in general and export response in particular is highlighted. Policy analysis reveals difficult trade‐offs between short‐run mitigation and long‐run growth. Improved agricultural productivity has powerful positive impacts, but remains difficult to achieve and may not address the immediate impacts of higher prices.     

Bioenergy in Southern Africa: An opportunity for regional integration?

ABSTRACT

This introductory paper sets out the rationale for revisiting questions surrounding biofuel futures in Southern Africa and exploring the case for the establishment of a regional market. This contrasts with most research that has focused upon benefits and risks of production and consumption for individual countries. The analysis in this issue suggests that while benefits exist, the key challenges that have stifled production and consumption to date would need to be overcome. Unlocking trade requires relaxing requirements for South African manufacturers to source all their feedstock domestically. Key among factors to encourage production is resolving agricultural investment processes, particularly designing inclusive business models and clarifying land acquisition processes.
