Due Dates and RCPSP
2006
Due dates are an essential feature of real projects, but little effort has been made in studying the RCPSP with due dates in the activities. This paper tries to bridge this gap by studying two problems: the TardinessRCPSP, in which the objective is total tardiness minimization and the DeadlineRCPSP, in which the due dates are strict (deadlines) and the objective is makespan minimization. The first problem is NP-hard and the second is much harder, since finding a feasible solution is already NP-hard. This paper has three objectives: Firstly to compare the performance on both problems of well-known RCPSP heuristics - priority rules, sampling procedures and metaheuristics - with new versions w…
“Let’s make lots of money”: the determinants of performance in the recorded music sector
2017
This research analyzes the performance of 467 record labels in eight European countries over a period of 13 years (2003-2015). The main goal is to explain a relative measure of profitability in terms of observed variables, although the nature of the dataset also allows us to include non-observed firm and country effects. To this end alternative models are estimated and three main research questions are tested, namely: (1) the effect of the dual structure of the recorded music market, in which a competitive segment and an oligopoly coexist; (2) the extent and source of the volatility of profits in record labels; and (3) the nonlinear impact of size on performance.
Economic sustainability of early potato production in the Mediterranean area
2014
The interactions between a given commercial enterpr ise, its territory and development, have become a key issue in recent years. Theories of economic dev elopment tell us that a territory may undergo development provided viable, economically sustainab le commercial activities exist. Based on the latter postulate, the present paper analyzes the economic sustainability of farming enterprises growing early potatoes in a Mediterranean setting. In particular, the study was conducted in south-eastern Sicily, island in the centre of the Mediterranean. The resu lts underscore their modest profitability, mainly d ue to a lack of entrepreneurial strategies aimed at en hancing production. This situati…
The scent of Mare Nostrum : medicinal and aromatic plants in Mediterranean soils
2012
In the Mediterranean area, the simultaneous occurrence of pedological, climatic and economic constraints often sets a limit on the profitability of agriculture, and farmers are forced to grow a reduced number of species, dealing with a secure—albeit low—market income. The introduction of medicinal and aromatic plants (MAPs) inside the current farming systems could represent a useful means to meet the multifunctional role of agriculture: producing safe food, in respect of the environment, and contributing to the development of rural areas. The study of the relationships between MAPs and the soils in which they may be grown may have two approaches: (1) the evaluation of yield and qualitative …
Should Microfinance Institutions diversify or focus? A global analysis
2018
Abstract This paper investigates the effects of revenue diversification on the financial performance of microfinance institutions (MFIs). The long-standing question about whether financial institutions should diversify or focus is a topic of ongoing debate. Using a global sample of MFIs, we investigate which view is appropriate for microfinance institutions. The results show that, diversification across revenue streams improves sustainability and profitability of MFIs. This suggests that revenue diversification is an important strategy for the sustainability of microfinance.
Measuring microfinance performance
2015
MFIs are measured according to two dimensions. One is their outreach to poor people, that is, their ability to provide poor families access to financial services. This is the MFIs’ social mission. The other dimension is their financial sustainability, that is, their ability to pay their employees, lenders, and other suppliers, in short, their ability to produce a profit from their operations. We set out the main microfinance measures and confirm earlier findings that profitability is rather weak in microfinance, and that operational costs constitute a large part of the total costs. We argue that researchers should put more efforts into identifying the MFI’s cost drivers because social outre…
Risk-Managed 52-Week High Industry Momentum, Momentum Crashes, and Hedging Macroeconomic Risk
2017
This is the first study that investigates the profitability of Barroso and Santa-Clara’s (2015) risk managing approach for George and Hwang’s (2004) 52-week high momentum strategy in an industrial portfolio setting. The findings indicate that risk-managing adds value as the Sharpe ratio increases, and the downside risk remarkably decreases. Even after controlling for the spread of the traditional 52-week high industry momentum strategy in association with standard risk-factors, the risk-managed version generates economically and statistically significant payoffs. Notably, the risk-managed strategy is partially explained by changes in cross-sectional return dispersion, whereas the traditiona…
The Impact of Monetary Policy on Bank Profitability
2020
This chapter analyzes the effect of the monetary policy on both net interest margin and bank profitability using a panel data from 31 OECD countries over the period 2000–2017. The main results show that expansionary monetary policy measures adopted in numerous economies had a negative impact on net interest margins and, therefore, on bank profitability. The relationship between interest rates and the slope of the yield curve with both the net interest margin and profitability is non-linear, more specifically concave. This suggests that the negative impact of low interest rates and the flat yield curve is greater the lower and flattened they are, respectively. Therefore, a potential normaliz…
Ambidextrous Leadership, Social Entrepreneurial Orientation, and Operational Performance
2019
In the knowledge era, new forms of organizing and managing firms emerge to adapt to new situations. One such new form of organizational management is ambidextrous leadership. Ambidextrous leadership combines opening leader behaviors, such as promoting creativity, and closing leader behaviors, such as accomplishing objectives and adhering to norms. Thus, the aim is to demonstrate that a social orientation is not at odds with measures of operational performance other than profitability. The purpose of this study is to examine how ambidextrous leadership is linked to social entrepreneurial orientation and how this in turn affects operational performance. This is done through a rigorous review …
An original multi-objective criterion for the design of small-scale polygeneration systems based on realistic operating conditions
2008
The optimal design and operation of cogeneration and trigeneration systems for buildings applications is a complex issue, which has been investigated by several different approaches. Both the two basic management strategies, namely heat-tracking and electricity-tracking, have advantages and drawbacks in terms of operating results and may lead the plant designer either to undersize or oversize the CHP unit with respect to the optimal lay-out. Experimental works have demonstrated how the actual on-site performance of small-scale polygeneration systems significantly differs from their expected operation, due to the need for a regular plant operation and the effects of outages for scheduled or …
