An entrepreneur's social capital and performance: the role of access to information in the Argentinean case
2012
Purpose - The aim of this paper is to analyze the impact of an entrepreneur's social capital on their access to information, and how such access improves the performance of their entrepreneurial project. Design/methodology/approach - A structural equations model (SEM) is estimated and validated from a database including information from 282 Argentinean entrepreneurs who answered a questionnaire specifically designed for this research. The analysis of this model allowed the impact of dependent latent variables on the performance of the start-up to be determined. Findings - The performance of an entrepreneurial project depends on an entrepreneur's access to finance, markets and information. S…
NASH EQUILIBRIA IN A MODEL OF MULTIPRODUCT PRICE COMPETITION: AN ASSIGNMENT PROBLEM
2003
We study the market interaction of a finite number of single-product firms and a representative buyer, where the buyer consumes bundles of these goods. The buyers' value function determines their willingness to pay for subsets of goods. We show that subgame perfect Nash-equilibrium outcomes are solutions of the linear relaxation of an integer programming assignment problem and that they always exits. The (subgame perfect) Nash-equilibrium price set is characterized by the Pareto frontier of the associated dual problem's projection on the firms' price vectors. We identify the Nash-equilibrium prices for monotonic buyers' value functions and, more importantly, we show that some central soluti…
The Convenience of Applying Multilevel Modeling on Real Estate Valuation
2015
There are many economic agents interested in valuing big amounts of real estate assets. One of these agents are the financial institutions, which must value their vast mortgage portfolios periodically. In this paper we analyze the use of the Hierarchical Linear Model to value real estate portfolios. This model gives valuable information compared with the traditional OLS models and is more accurate, as it takes into account the hierarchical structure of the data.

Guanxi, performance and innovation in entrepreneurial service projects.
2012
This paper analyzes the role played by two dimensions of entrepreneurs’ private social capital in the survival, growth and innovativeness of entrepreneurial service ventures: local size and preferential attachment degree. We build a bi-dimensional measure of social capital based on network models and a methodology to estimate this measure for any group of entrepreneurs. Based on a survey of service entrepreneurs who launched their business in the city of Shanghai, we show that roles played by each dimension are quite different. A large local size of the network increases the chances of survival of the new venture. However, the chance to become a dynamic venture is only related to entreprene…
Do irresponsible corporate activities prevent membership in sustainable stock indices? The case of the Dow Jones Sustainability Index world
2021
Abstract The study analyses the real-life results from the DJSI World selection process and investigates whether companies are treated differently because of sectoral or geographical diversification needs of the index; furthermore, the question whether its methodology penalises ESG-related irresponsible corporate activities is investigated. The last is an important issue, as it is not unusual to find constituents of sustainable indices implicated in corporate scandals. This is a striking fact, contradicting the ethical and sustainable imperative such companies are supposed to comply with. The authors scrutinise data from a data panel containing 2872 firms between 2011 and 2016 and estimate …
A Model for Estimating Cash Flows in Firms Backed by Venture Capital
2013
Venture Capital only backs firms for a short period of time. When the time to exit arrives, the firm must inevitably be valued in order to obtain a basis for negotiating the exit price. Discounted cash flow is precisely one of the valuation methods that are used most by Small and Medium-sized Enterprises (SMEs).
Is full banking integration desirable?
2020
The aim of this paper is to analyze the links between banking integration and economic development for a sample of OECD countries. We measure banking integration considering state-of-the-art indicators that measure not only how open a banking system is but also its degree of connectedness with other banking systems. In a second stage, we plug these indicators in a model of economic growth, also controlling for other relevant variables considered by the economic growth literature. In contrast to previous initiatives, this second stage explicitly takes into account the differing levels of economic development of the countries in our sample, since the benefits of enhanced banking inte- gration…
Mass appraisal of residential real estate using multilevel modelling
2016
Mass appraisal, or the automatic valuation of a large number of real estate assets, has attracted the attention of many researchers, who have mainly approached this issue employing traditional econometric models such as Ordinary Least Squares (OLS). However, this method does not consider the hierarchical structure of the data and therefore assumes the unrealistic hypothesis of the independence of the individuals in the sample. This paper proposes the use of the Hierarchical Linear Model (HLM) to overcome this limitation. The HLM also gives valuable information on the percentage of the variance error caused by each level in the hierarchical model. In this study HLM was applied to a large dat…
A network perspective on international banking integration
2011
Abstract The aim of this article is to develop new international banking integration indicators together with their components: openness and regularity (balance) of the bilateral bank flows. We define the Standard of Perfect Banking Integration (SPBI), which characterizes the scenario attainable when bank flows are not geographically biased, and cross-border asset trade is not affected by home bias. We assess the gap between a hypothetical scenario of geographic neutrality and the current level of banking integration, along with both of its components. The empirical application to the banking systems of 23 countries over the 2003–2009 period enables us to conclude that the level of banking …

The questionnaire allows the authors to identify the social network of the entrepreneurs, estimate the empirical degree distribution for the entire sample, and estimate local size and preferential attachment degree.FindingsThere is empirical evidence that entrepreneurs do not create social ne…
The Inclusion of Socially Irresponsible Companies in Sustainable Stock Indices
2019
Social rating agencies implement complex filters to identify the companies with the best sustainable and social performance and help investors select the companies for their sustainable portfolios. This study analysed whether companies that are defined as ethical, sustainable and socially responsible by those agencies actually deserve this label. More specifically, the inclusion in the prestigious Dow Jones Sustainability Index (DJSI) World of companies that have been involved in controversies according to the Thomson Reuters Eikon database was studied. The results show that the inclusion of irresponsible companies in the DJSI Index is a fact. This outcome is in line with previous studies t…
Multiproduct trading with a common agent under complete information: Existence and characterization of Nash equilibrium
2014
This paper focuses on oligopolistic markets in which indivisible goods are sold by multiproduct firms to a continuum of homogeneous buyers, with measure normalized to one, who have preferences over bundles of products. Our analysis contributes to the literature on private, delegated agency games with complete information, extending the insights by Chiesa and Denicolò (2009) to multiproduct markets with indivisibilities and where the agent's preferences need not be monotone. By analyzing a kind of extended contract schedules -mixed bundling prices- that discriminate on exclusivity, the paper shows that efficient equilibria always exist in such settings. There may also exist inefficient equil…
Statistical formats to optimize evidence-based decision making: A behavioral approach
2013
Abstract Statistical information is crucial for managerial decision making. The decision-making literature in psychology and mathematical cognition documents how different statistical formats can facilitate certain types of decisions. The present analysis is the first of its kind to assess the impact of statistical formats in the presentation of data from market research on both the optimality of market decisions and the time required to perform the decision-making process. An economic experiment provides the data for this study. The experiment presents statistical information in simple frequencies and relative frequencies using numerical and pictorial representations in the context of diff…
Modelling agricultural risk in a large scale positive mathematical programming model
2020
International audience; Mathematical programming has been extensively used to account for risk in farmers' decision making. The recent development of the positive mathematical programming (PMP) has renewed the need to incorporate risk in a more robust and flexible way. Most of the existing PMP-risk models have been tested at farm-type level and for a very limited sample of farms. This paper presents and tests a novel methodology for modelling risk at individual farm level in a large scale model, called individual farm model for common agricultural policy analysis (IFM-CAP). Results show a clear trade-off between including and excluding the risk specification. Albeit both alternatives provid…
REPEATED GAMES WITH PROBABILISTIC HORIZON
2005
Repeated games with probabilistic horizon are defined as those games where players have a common probability structure over the length of the game's repetition, T. In particular, for each t, they assign a probability pt to the event that "the game ends in period t". In this framework we analyze Generalized Prisoners' Dilemma games in both finite stage and differentiable stage games. Our construction shows that it is possible to reach cooperative equilibria under some conditions on the distribution of the discrete random variable T even if the expected length of the game is finite. More precisely, we completely characterize the existence of sub-game perfect cooperative equilibria in finite s…
Asymmetric modeling of organizational innovation
2015
[EN] This study revisits the theory, data, and analysis in Hervas-Oliver and Sempere-Ripoll (2014) and applies fuzzyset qualitative comparative analysis (fs/QCA) to organizational innovation effects and the influence on them of technological innovations. The influence of technological innovations (product and process) on organizational innovation and its effects is an inconclusive debate. Using fuzzy set comparative qualitative analysis (fs/QCA) on Hervas-Oliver and Sempere-Ripoll’s (2014) 9,369 organizational innovators, the present study offers more complex and nuanced antecedent conditions relating to organizational innovation beyond Hervas-Oliver and Sempere-Ripoll (2014) analysis based…
Measuring Globalization of International Trade: Theory and Evidence
2009
Measuring globalization requires a Standard of Perfect International Integration as a benchmark that a single world space would reach under conditions of geographic neutrality in international trade. We define this standard and present indicators for openness, connectedness and integration, for each specific economy, and for the world economy. We apply our indicators to data on trade flows for 59 countries for the 1967-2004 period. Results show that trade integration is higher than what traditional openness indicators suggest. Several economies find high levels of integration, but the low degree of openness in some large economies jeopardizes the progress of globalization. © 2008 Elsevier L…
Explaining local governments' cost efficiency: Controllable and uncontrollable factors
2020
Abstract Efficient and effective management of public resources is essential at all levels of government. This issue has gained momentum due to the strains that affected public sector finances after the onset of the 2007/08 crisis in many countries, particularly in Europe. In this article, we evaluate the influence of environmental variables that affect local government efficiency in one European country, Spain, during the crisis years (2009–2015). To this end, and considering the possible influence of both controllable and uncontrollable factors, we use an approach that is able to analyse their impact across the conditional distribution of performance, and which controls for the (likely) e…
Modélisation du comportement des agriculteurs face au risque dans un modèle de programmation mathématique positive (PMP) à grande échelle
2017
Agricultural production is characterized for being a risky business due to weather variability, market instability, plant diseases as well as climate change and political economy uncertainty. The modelling of risk at farm level is not new, however, the inclusion of risk in Positive Mathematical Programming (PMP) models is particularly challenging. Most of the few existing PMP-risk approaches have been conducted at farm-type level and for a very limited and specific sample of farms. This implies that the modelling of risk and uncertainty at individual farm level and in a large scale system is still a challenging task. The aim of this paper is to formulate, estimate and test a robust methodol…
Trade integration in the European Union: Openness,interconnectedness, and distance
2020
Abstract This article presents a set of indicators to measure regional trade integration, focusing on the case of the European Union. We propose measures of openness, connectedness and integration which are tuned to evaluate not only how these components contribute to the advance of international integration, but also to control for the potential threat posed by the proliferation of regional trade agreements to trade globalization. Although this and related questions have been examined from several perspectives, the present article explicitly attempts to quantify how regional trade agreements either intensify or thwart trade globalization. Results show that the process of trade integration …
Are social and entrepreneurial attitudes compatible?
2012
PurposeThe aim of this paper is to analyze the compatibility between entrepreneurial and social attitudes. Specifically, it seeks to analyze whether subjects with a more developed economic entrepreneurial attitude exhibit a less social attitude.Design/methodology/approachThe methodology integrates an economic experimental approach with a standard entrepreneurial intention questionnaire to analyze the interaction between entrepreneurial and social self‐perceptions and behavior.FindingsThere is empirical evidence that experimental entrepreneurial behavior (characterized by detecting an opportunity and accepting risk to take an economic advantage from it in laboratory experiments) reduces the …
Identification of efficient equilibria in multiproduct trading with indivisibilities and non-monotonicity
2018
Abstract This paper focuses on multiproduct trading with indivisibilities and where a representative agent may have non-monotonic preferences. In this framework, the set of firms’ profits (which comes from efficient subgame perfect Nash equilibria) is the Pareto frontier of some projection of the core of the game. We show that under monotonicity efficient subgame perfect Nash equilibria are achieved by single offers and the equilibrium characterization is easy to obtain. When dealing with non-monotonic preferences the problem becomes more challenging. Then, we define a pair of primal–dual linear programming problems that fully identifies the core of the game. A set of modified versions of t…
