Are private schools more efficient than public schools ? Evidence from Tanzania
2001
International audience; Beginning in the mid-1980s, there has been an explosive growth of private secondary schools in Tanzania. By easing constraints on private operators, the government has clearly found an effective way in the context of right public budget constraints to cope with the excess demand for this level of schooling. But has the policy also led to efficient operations in terms of student learning ? In this paper, we attempt to shed light on this issue by comparing the efficiency of four types of schools that make up the majority of schools in the country : Government and Community schools in the public sector, and Chirstian and Wazazi schools in the private sector. Using longi…
Nonlinearity in intergenerational income transmission: A cross-country analysis
2016
Abstract The aim of this paper is to explore nonlinearity in intergenerational income transmission. We use a set of occupational tables in different countries to test nonlinearity. We also empirically address how policy variables can affect nonlinearity. Our findings suggest that concavity is supported in those societies with less credit constraints, but with more poverty and income inequality; education has an increasing effect on convexity.
Bubbles and Crowding-in of Capital via a Savings Glut
2017
This paper uncovers a mechanism by which bubbles crowd in capital investment. If capital formation is initially depressed by a binding credit constraint, a bubble triggers a savings glut. Higher returns in a new bubbly equilibrium attract additional savings, which are channeled to expand investment at the extensive margin, leading to permanently higher capital, output, and wages. We demonstrate that crowding-in through this channel is a robust phenomenon that occurs along the entire time path.
Does a voluntary conservation program result in a representative protected area network?
2009
Abstract Conservation contracting has attained growing interest worldwide as a tool for protecting biodiversity in privately owned lands. In this policy, landowners receive payments from an environmental agency in exchange for land use practices that contribute to the supply of biodiversity. This approach may result in a conservation network which does not cover all focal ecological characteristics, because landowners determine the supply of potential targets. In addition, the contracts are typically allocated by using a scoring method that is not giving information on the representativeness of the species composition of the sites. In this study, we investigated what is the performance of a…
In search of family business continuity: the case of transgenerational family entrepreneurship
2011
This qualitative case study analyses continuity of transgenerational entrepreneurship in the family business. Transgenerational entrepreneurship is based on multigenerational, and in this particular firm, on the founder and next generation, business activities in the same family business. Methodologically, the data was collected by interviewing members of two generations of Imagon Ltd.; the founder, and his sons. Imagon Ltd. shows signs of transgenerational continuity. It did not start off that way in the founder’s mind; his desire was just to work for himself and fulfil his own visions. It was only much later that the prospect of defining his company as a family business entered the pictur…
The regulatory environment and financial constraints of private firms in the European Union
2023
This study analyzes the influence of the institutional environment on firms' capital structure in the European Union (EU). Unlike other research, we focus on private firms and include data from all EU countries from 2010 to 2018. We split the sample into groups of small and large firms, which we consider financially constrained and unconstrained, respectively. Throughout the study, we posit that institutional effects on financing policies vary with size, with the effects being greater for constrained firms as they face more financing frictions. We also run regression models controlling for firm-level characteristics and relevant macroeconomic factors. Our findings reveal that a high-quality…
A PROJECT-POSED APPROACH TO REAL BODY DYNAMICS: THE ROLE OF CONSTRAINTS IN ELASTIC WAVE PROPAGATION
2010
In this paper we present some results of a project-posed approach to the teaching of mechanical wave propagation focused on observations and measurements of wave properties in solids and on modelling of these properties by using different simulation tools. In particular, the propagation speed of sound waves in metallic rods is studied by using simple experimental arrangements based on the measurements of contact times between a small body and long metallic rods with which the body can collide. An interesting effect of this approach is the revision of students’ ideas about the rigid body model, studied at high school or college level and usually hardly followed by deepening on the fundamenta…
Abstract Estimates of the Rate of Convergence for Optimal Control Problems
1997
A method for solving optimal control problems with general elliptic operators is presented and analyzed. Especially, estimates of the rate of convergence for the control problems with the proposed approach are derived independently of the underlying approximation method. Some numerical experiments with the proposed method are included.
Seeking the Important Nodes of Complex Networks in Product R&D Team Based on Fuzzy AHP and TOPSIS
2013
Published version of article in the journal: Mathematical Problems in Engineering. Alo available from the publisher at: http://dx.doi.org/10.1155/2013/327592 Open Access How to seek the important nodes of complex networks in product research and development (R&D) team is particularly important for companies engaged in creativity and innovation. The previous literature mainly uses several single indicators to assess the node importance; this paper proposes a multiple attribute decision making model to tentatively solve these problems. Firstly, choose eight indicators as the evaluation criteria, four from centralization of complex networks: degree centrality, betweenness centrality, closeness…
