Household and market production of families in a late nineteenth century American city

Urban families in the late nineteenth century depended upon their children as their most important source of labor income apart from the male head of house-hold. This paper explores the determinants of the labor force participation of children over 10 years old within the context of the economic theory of household and market production, using microlevel data from 1880 Philadelphia. The father's income and unemployment, the presence of the mother or father, boarders, servants, older and younger siblings, parents' literacy, and ethnicity, among other variables, are used in a probit analysis of the labor force participation of children. The results validate the economic theory of household and market production demonstrating, in particular, substitution between mothers and their daughters and the role of comparative advantage in family decisions concerning the allocation of their members' time. Ethnic differences were only important for daughters.     

The estimation of agricultural policy effects on soil erosion—An application for the bio-economic model MODAM

As agricultural policies affect land use, they have effects on the amount of soil erosion in agricultural regions through changes of the economic conditions of agricultural production. Prices of inputs and outputs, regulations and incentives can change, forcing or encouraging farmers to adopt new crop rotations. This paper shows how a bio-economic model can be used to describe and estimate the effects of policies on agricultural production and the risk of soil erosion at the example of a region in North-Eastern Germany. The model uses both an assessment tool that is based on a fuzzy-logic approach for the estimation of soil erosion risk of cropping practices, and a linear programming model, that simulates farmers’ economic behaviour under the assumption of gross margin maximisation being the main goal of farmers’ actions.The analysed policy options were both a targeted and an untargeted incentive programme for reduced tillage, and a restriction option where high erosive crops are not allowed on high erodible field types. The results show that policy changes can have an impact on soil erosion. Furthermore, soil conservation policies are shown to have different levels of efficiency in terms of reduced soil erosion related to the costs of the policy. In the case of this study, a restriction option was more efficient than the incentive options. The results of such simulations can serve as a decision support for the development of soil conservation policies and help to foresee the effects of general changes of agricultural policies.     

Glück — Die Sicht der Ökonomie

Glück führte lange Zeit ein Schattendasein in der ?konomischen Forschung. Das hat sich seit einigen Jahren ge?ndert. Aus den neuen Erkenntnissen zu den wirtschaftlichen und au?erwirtschaftlichen Bestimmungsgründen des Glücks werden auch Empfehlungen für eine Wirtschaftspolitik abgeleitet, die das pers?nliche und gesellschaftliche Glück der Menschen berücksichtigt. Bruno S. Frey und Claudia Frey Marti fassen in diesem Beitrag ihr Buch¹ zu dem Thema zusammen.     

The Italian airport industry in transition: a performance analysis

This paper analyzes the impacts of Italian government actions on the efficiency of 36 airports between 2001 and 2003. The changes have included privatization, enlargement of the services provided directly by airport management companies, through the modification of the concession agreements, and the creation of two hubs. The analysis, using the consolidated two-stage data envelopment analysis with bootstrapping, indicates that airports with a majority public holding are on average more efficient and the presence of two hubs is source of inefficiency.     

On the relationship between financial inclusion and bank performance

This study examines the relationship between various financial inclusion measures and banks' performance across multiple countries with varying institutional, regulatory and income levels. To construct an aggregate bank performance index, we employ principal component analysis, which utilises a set of critical indicators summarised by the CAMEL rating system, including banks' solvency, asset quality, efficiency, profitability and liquidity. Our primary findings indicate that different measures of financial inclusion exhibit varying associations with bank performance. Specifically, there is a trade-off between bank performance and credit deepening, especially in high-income nations. Conversely, in low-income nations, higher financial inclusion, measured by deposits to GDP, number of deposits, and number of borrowers, does not affect bank performance adversely. Banks in low-income nations could achieve significant gains by improving financial access and enhancing regulatory environments.     

Functions of scenarios in transition processes

Given the interplaying tendencies of economic decline, social instability, and environmental depletion, any transition towards sustainable development faces a challenging task. To successfully cope with this complexity requires transition management. Integrated approaches for supporting sustainability transitions have been elaborated in the last years. Future studies and scenario construction are regarded as essential components in these approaches. However, the related studies in this field have focused either on a specific type of transition process, or on decision support in a different contextual process, or on a specific function of scenarios. Thus, an evaluation of the wide range of viewpoints on the functions of scenarios with respect to the requirements for transition management is still missing. In this paper, we systematically elaborate upon the functions for transition management that scenarios can fulfil. The developed concept is applied to five empirical scenario studies supporting transition processes on the national, regional and local level in Switzerland. The paper contributes to the development of a functional methodology of transition support, providing initial guidelines for answering the question of which method is appropriate for what type and phase of a transition process.
