Ambidexterity in micro and small firms: Can competitive intelligence compensate for size constraints?
2021
Ambidexterity has been linked to firm structures that are typical of organizations with a larger size. However, further research is needed to analyze whether the effect of firm size on ambidexterity is contingent on other aspects. We argue that micro and small firms that have developed some competitive intelligence routines (CIRs) may foster ambidextrous behavior and compensate for the limitations arising from a smaller size and lack of resources. We test our proposal on a sample of 200 firms in the furniture sector. Our results show that CIRs compensate for size constraints in that size is no longer a relevant variable to increase ambidextrous behavior in firms that achieve higher levels i…
Pricing of forwards and other derivatives in cointegrated commodity markets
2015
Abstract We analyze cointegration in commodity markets, and propose a parametric class of pricing measures which preserves cointegration for forward prices with fixed time to maturity. We present explicit expressions for the term structure of volatility and correlation in the context of our spot price models based on continuous-time autoregressive moving average dynamics for the stationary components. The term structures have many interesting shapes, and we provide some empirical evidence from refined oil future prices at NYMEX defending our modeling idea. Motivated from these results, we present a cointegrated forward price dynamics using the Heath–Jarrow–Morton approach. In this setting, …
From custom to law, an economic rationale behind the black lettering
2018
This article employs the number of rule recipients in order to explain the transformation of some customs into laws. The publication of rules may mark the reaching of the threshold number beyond which the spontaneous rule leaves room for the State intervention. In addition, the publication resolves a couple of questions that Hayek left unresolved. Examples are provided from ancient merchant customs and contemporary international law.
A quantitative-based model to assess seed accelerators’ performance
2021
Seed accelerators are a new generation of business incubators. While the number of seed accelerators worldwide has grown exponentially, there is as yet no consensus on how to measure and analyse th...
A new approach to modelling the input-output structure of regional economies using non-survey methods
2021
AbstractThis paper proposes a new approach to the regionalization of national input–output tables where suitable regional data are scarce and analysts are considering using location quotients (LQs). We focus on the FLQ formula, which frequently yields the best results of the pure LQ-based methods, and develop an enhanced way of implementing this approach. We use a modified cross-entropy (MCE) method, along with a regression model, to estimate values of the unknown parameter δ in the FLQ formula, specific to both region and country. An analysis of survey-based data for 16 South Korean regions reveals that the proposed FLQ+ approach yields more accurate estimates of both input coefficients an…
Model Based Monte Carlo Pricing of Energy and Temperature Quanto Options
2010
Weather derivatives have become very popular tools in weather risk management in recent years. One of the elements supporting their diffusion has been the increase in volatility observed on many energy markets. Among the several available contracts, Quanto options are now becoming very popular for a simple reason: they take into account the strong correlation between energy consumption and certain weather conditions, so enabling price and weather risk to be controlled at the same time. These products are more efficient and, in many cases, significantly cheaper than simpler plain vanilla options. Unfortunately, the specific features of energy and weather time series do not enable the use of …
Synergistic effects and the co-existence of networks in clusters
2016
AbstractNetwork systems like clusters are characterized by the coexistence of relational architectures with ties and nodes of different nature. While recent research has analysed how a set of structural features shape the dynamics and effects of one cluster network, the outstanding question is to what extent such features and outcomes are influenced by the concomitance of distinct content-related linkages. This paper integrates both network and evolutionary economic geography perspectives to develop and test a model that links innovation performance with the benefits that stem from technical and business relations. Data collected in a biotech cluster in the Valencia region (Spain) demonstra…
Alternative tuition fees schemes: a simulation exercise
2021
In this paper we use a theoretical model of effort optimization on the part of university students to simulate the effects of different tuition fees schemes. For each of such schemes, we present an...
Leadership Manipulation and Ethics in Storytelling
2012
This article focuses on exerting influence in leadership, namely manipulation in storytelling. Manipulation is usually considered an unethical approach to leadership. We will argue that manipulation is a more complex phenomenon than just an unethical way of acting in leadership. We will demonstrate through an empirical qualitative study that there are various types of manipulation through storytelling. This article makes a contribution to the literature on manipulation through leadership storytelling, offering a more systematic empirical analysis and a more nuanced view of the topic than previously existed by outlining how managers engage in manipulative storytelling and what kind of ethics…
Outsourcing and efficiency: the case of Spanish citrus farming
2006
Outsourcing in agriculture has traditionally been seen as a managerial strategy of smaller farms to achieve higher levels of efficiency. In this article, we provide empirical evidence supporting the existence of a positive relationship between outsourcing and efficiency in Spanish citrus farming. Outsourcing is measured by the proportion of outsourced labor and capital in farms' total use of these production factors, i.e., the higher the proportion of outsourced inputs, the higher the degree of outsourcing. Making use of data envelopment analysis techniques, we compute input-specific reductions required to achieve technical efficiency at the farm level. Our results show that attainment of t…
