This paper applies recent developments in collective model estimation to elicit the household resource sharing rule, i.e. the amount of household resources accruing to fathers, mothers, and their children among African families in South Africa. We use the 2010/11 South African Income and...

We propose a novel structural method to empirically identify economies of scale in household consumption. We assume collective households with consumption technologies that define the public and private nature of expenditures through Barten scales. Our method recovers the technology by solely...

We study the fiscal consequences of municipal mergers by making use of a largescale merger reform in the German federal state of Brandenburg. This reform, which was implemented from 2001 to 2003, led to a substantial reduction in the number of municipalities. Individual mergers were...

Potable water supply in Germany is highly fragmented. A consolidation of the industry could, therefore, lead to lower cost of water supply and price savings for the customers. In this paper we estimate a total cost function for potable water supply based on a unique sample of German water...

Are there economies of scale to data in internet search? This paper is first to use real search engine query logs to empirically investigate how data drives the quality of internet search results. We find evidence that the quality of search results improve with more data on previous searches....

This study compares the responsiveness of microcredit interest rates to age, scale of lending and organisational charter. It uses an unbalanced panel of 300 MFIs from 107 developing countries from 2005 to 2015. Three key trends emerge from the results of a 2SLS regression. First, the adoption of...

This study investigates the legitimacy of the relatively high interest rates charged by those microfinance institutions (MFIs) which have been transformed into regulated commercial banks using information garnered from a panel of 1232 MFIs from 107 developing countries. Results show that...

This paper discusses the process of European institutional integration from a political-economy perspective, linking the long-standing political debate on the nature of the European project to the recent economic literature on political integration and disintegration. First, we introduce the...

Specialization in agricultural systems leads to trade-offs between economic gains and ecosystem functions. Economic gains can be maximized when production activities are specialized at increasingly broader scales (from the household to the village, region or above), particularly when markets for...

I compare returns to scale in the U.S. and Canadian banking system from 1996 to 2015. I estimate a parametric trans-log cost function and, for robustness, an inputoriented distance function. I do this in a way that is commensurate with the limitations of these models. Among the ten largest...

The asset pricing literature demonstrates a positive association between operating leverage and expected stock returns. We uniquely examine the predictive power of operating leverage on expected stock returns, in light of the industry returns to scale. Our inspection starts with a theoretical...

The paper unveils the market structure of container shipping, which suffers by many interpretations. Existing models regress between contestability, duopoly, monopolistic competition and game theory. This paper proposes an oligopoly model with two groups of companies: oligopolists and...

We study the fiscal consequences of municipal mergers by making use of a largescale merger reform in the German federal state of Brandenburg. In addition to being the first evaluation of an East-German merger reform, this study contributes to the literature by exploring the fiscal consequences...

This paper reconsiders the link between welfare state provision, globalisation and competitiveness empirically. We challenge the conventional wisdom that welfare states, large-scale public provision of social insurance and progressive systems of redistributive taxation are incompatible with...

In this paper, we compare subjective and money-metric measures of poverty in South Africa using data collected in the 2008/09 Living Conditions Survey. In addition to collecting detailed information on expenditure, the survey asked respondents to provide an assessment of the economic status of...

The energy efficiency of the residential housing stock plays a key role in strategies to mitigate climate change and global warming. In this context, it is frequently argued that private investment and the quality of thermal upgrades is too low in the light of the challenges faced and the...

Empirical evidence on economies of scale in healthcare is mostly based on the cost effects of hospital mergers. In contrast to earlier studies, this paper approaches the economies of scale issue by analysing the break-ups of municipal health centre federations. We use the...

Mit mehr als 6 000 Versorgungsunternehmen ist die Trinkwasserversorgung in Deutschland stark fragmentiert. Hierdurch stellen sich Fragen nach möglichen Kostenvorteilen einer Konsolidierung des Sektors und daraus resultierenden Preissenkungsmöglichkeiten für die VerbraucherInnen. In diesem...

Scale characteristics are key properties of production functions that determine optimal firm sizes, and have considerable policy implications for sectors undergoing restructuring. However, estimates of scale characteristics typically vary with the assumptions of the underlying empirical model....

The pure model of replicator dynamics though providing important insights in the evolution of markets has not found much of empirical support. This paper extends the model to the case of firms vertically integrated in value chains. We show that i) by taking value chains into account, the...

The paper offers a complete analysis of the welfare-maximising capital investment and resource depletion policies in the Dasgupta-Heal-Solow-Stiglitz (DHSS) model with capital depreciation and any returns to scale. We establish a general existence result and show that an optimal admissible...

This paper addresses issue of sensitivity of efficiency classification of variable returns to scale (VRS) technology for enhancing the credibility of data envelopment analysis (DEA) results in practical applications when an additional decision making unit (DMU) needs to be added to the set being...
