Rising marginal cost and concavity of the production function

Suppose a production function, f, is continuous, quasi-concave and weakly monotone on the non-negative orthant of Euclidean n-space. Let c(·, ·) be the associated cost function. Then it is shown that f is concave if and only if for each w, c(w, ·) is convex.     

Regulating Rates of Return Do Gravitate in US Manufacturing!

In this paper we test for the gravitation of regulating return rates, namely those return rates yielded by capital goods incorporating the best methods of production. We define them within a vintage capital model taking into consideration capacity utilization, capital depreciation and wages of workers using past capital vintages. We consider two data sets regarding US manufacturing activities and we find that gravitation does take place. Our results are contrasted with those of the previous literature. Research and policy implications are discussed.     

Analyzing the welfare‐improving potential of land in the former homelands of South Africa

This article contributes to the debate on the role of land in reducing poverty in rural South Africa. It uses the year of arrival in the former homelands as an instrument for land access and size. This identification strategy is based on the fact that African households were forcibly relocated to the homelands during the apartheid. Due to increasing population pressure, later arrivals were less likely to be assigned land. The results show that land has a large positive effect on household welfare. Because the homelands are relatively disadvantaged areas, these results provide a lower bound for the positive effects of land on household welfare.     

Land distribution and inequality in a black settler colony: the case of Sierra Leone, 1792–1831†

Land distribution is considered to be one of the main contributors to inequality in pre‐industrial societies. This article contributes to the debate on the origins of economic inequality in pre‐industrial African societies by studying land inequality at a particularly early stage of African economic history. The research examines land distribution and inequality in land ownership among settlers in the Colony of Sierra Leone for three benchmark years over the first 40 years of its existence. The findings show that land inequality was low at the founding of the Colony but increased substantially over time. We suggest that this increase was enabled by a shift in the type of egalitarianism pursued by the colonial authorities, which was reflected in a change in the redistributive policy applied, which allowed later settlers to appropriate land more freely than had been previously possible.

Doing More with Less: The Disordinal Implications of Firm Age for Leveraging Capabilities for Innovation Activity*

Innovation requires the entrepreneurial capabilities of opportunity recognition and opportunity exploitation. Such capabilities generally accrue over time from a firm's cumulative learning and experience. In this study, we theorize that firm age should therefore moderate the firm's ability to leverage these capabilities for innovation activity, such that older firms can obtain higher outputs from their capabilities than younger firms can. We examine this relationship using a sample of 676 small and medium enterprises. We find that when both younger and older firms have highly developed innovation capabilities, older firms appear to enjoy higher levels of innovation activity than younger firms do. However, younger firms generally appear more likely to have higher levels of innovation activity than older firms do, when neither firm has highly developed innovation capabilities. We conclude with a discussion of the implications of these findings for research and practice.     

Why Are Themed Brandstores So Powerful? Retail Brand Ideology at American Girl Place

Although there is growing interest in themed brandstores, we still know very little about the source of these retail environments’ power to affect consumers profoundly. Utilizing an ethnographic study of American Girl Place, a culturally rich and highly successful retail environment, we find that effective retailing in these contexts is an intensely ideological affair. In our participant-observation of, and on-site interviews with, consumers at American Girl Place we find that the ideology of the brand manifests powerfully through a variety of different and distinct areas within the store: the Museum, the Library, the Café, the Salon, the Theater, and the Photo Studio. Ideological expression is central to each of these places. Tracking the influence of brand ideology through consumers’ retail experiences, we theorize about the centrality of retail place in ideological branding. Although the confluence of ideology and retailing has been referenced in prior research, this paper focuses on and systematically develops the theoretical interconnection between the two. The physical immediacy of themed brandstore experience acts as a quilting point that links together related cultural concepts into a strong retail brand ideology. The implications of this theory draw our attention to ideological and morally-bound retail brand expressions, emphasize the importance of a variety of retail formats within a single store, and provide practical guidelines for retailers eager to build successful brands of their own.     

Entrepreneurship in the public sector: a framework of analysis in European local governments

In this paper we explore the potential role of entrepreneurship in public sector organizations. At first, we present a review of the entrepreneurship theme in the political science and public management research streams, comparing these ideas with the mainstream business literature on entrepreneurship. Thereafter, we illustrate empirically how Stevenson's classical framework of entrepreneurship can be applied in a European local government context to explain the recent initiatives to compete for and utilize European Union structural funds. The empirical basis of the study is comprised of ten in-depth case studies of local government organizations, five in the UK and five in Italy. Finally, we propose five distinct types of entrepreneurial agents in the public sector: professional politician; spin-off creator; business entrepreneur in politics; career-driven public officer; and politically ambitious public officer.     

The dynamic of innovation networks: a switching model on technological change

In this paper, we introduce an agent-based model where heterogeneous firms compare and modify their innovation strategies, so generating an evolving network structure. By implementing dynamic behavioral switching via a fitness mechanism based on agents’ performance, companies can endogenously modify their tactics for technological change and switch among three groups: stand-alone innovators, collaborative innovators and imitators. On the one hand, we study the properties of the emerging networks and we show that they reproduce the stylized facts of innovation networks. Moreover, we focus the analysis on the impact of these three innovation categories on the macro economic aggregate, finding that collaborative companies are those having the highest positive impact on the economic system. On the other hand, we use the model to study the effect of different economic innovation policies in increasing macroeconomic performance.
