Are accounting majors really better? Evaluating admissions and retention standards for undergraduate accounting programs

Admission and retention standards for students in undergraduate programs of education are a widely-used tool for enhancing the quality of the students who complete these programs. The authors present a technique for evaluating the effectiveness of existing admission/retention standards and a discussion of the results of the application of the technique at a major midwestern university. The evaluation technique was found to provide a useful means of verifying the effectiveness of admission/retention standards in undergraduate accounting programs.     

The importance of the design of market-based instruments for CO2 mitigation: An AGE analysis for Spain

In the past few decades, economists have defended the use of market-based instruments (MBI) in environmental and climate policy. There have been many papers which have compared the costs of attaining environmental objectives with MBIs and with command and control instruments. However very few have compared different MBIs in examining these costs. This paper seeks to analyse various MBIs for CO₂ mitigation from the viewpoint of cost-effectiveness, using an AGE (applied general equilibrium) model for the case of Spain. A distinction is drawn between (1) quantity instruments, which represent different extents of a market for emission permits; and (2) price instruments, which represent different types of tax. Each instrument can affect different segments of the emission sources and therefore can have very different effects on the economy as a whole. We show how MBI can help to minimise mitigation costs, but also how taxes and tradable emission permits that are limited or constrained by many exemptions and distortions can raise costs considerably.     

Adverse selection, volume and transactions around dividend announcements in a continuous auction system

We show that liquidity providers do not significantly respond to changes in information asymmetry risks, at least when we analyse their trading behaviour around dividend announcements of a representative sample of stocks in a continuous auction trading mechanism. the implicit bid-ask spread does not seem to change beyond what is normally conveyed through an increased number of transactions. We also document that the information in the trading behaviour of investors is primarily contained in the number of daily transactions.     

On the bi-dimensionality of liquidity

Variations in overall liquidity can be measured by simultaneous changes in both immediacy costs and depth. Liquidity changes, however, are ambiguous whenever both liquidity dimensions do not reinforce each other. In this paper, ambiguity is characterized using an instantaneous time-varying elasticity concept. Several bi-dimensional liquidity measures that cope with the ambiguity problem are constructed. First, it is shown that bi-dimensional measures are superior since commonalities in overall liquidity cannot be fully explained by the common factors in one-dimensional proxies of liquidity. Second, it is shown that an infinitesimal variation in either market volatility or trading activity augments the probability of observing an unambiguous liquidity adjustment. Ambiguity strongly depends on the expected (deterministic) component of volatility.     

The Effect of Enhancing Workers’ Employability on Small and Medium Enterprises: Evidence from Spain

In this paper, we analyse the effect of promoting workers’ employability on labour productivity. To this end, we adapt a simple efficiency-wage model that includes the employer’s decision on the provision of opportunities for enhancing workers’ employment prospects in a context of job insecurity. We show that (i) by facilitating workers’ employability, the firm increases its labour productivity; and (ii) the higher the job uncertainty the higher the productivity gains due to the increase in employability. One of the advantages of our model is that it is simply enough to allow us to formulate two testable hypotheses, namely (i) the increase of jobs’ potential to enhance workers’ employability results in higher level of workers’ effort, and (ii) the provision of employability is more profitable for small and medium enterprises (SMEs) than for large firms. More precisely, SMEs should obtain higher effort levels from employees by fostering workers’ employability than large firms. We provide some evidence supporting these hypotheses from a highly representative sample of Spanish manufacturing firms. This research has been funded by the Spanish Ministry of Education and Science, project SEJ2004-07242-C03-02.     

Internationalization and entrepreneurial orientation of family SMEs: The influence of the family character

Internationalization is an important entrepreneurial strategy for promoting the long-term growth and survivability of small and medium-sized enterprises (SMEs). Family involvement in top management teams (TMTs) can explain the heterogeneous behaviors of these firms’ international entrepreneurship process. This paper analyzes the moderating effects of the family’s influence on the relationship between entrepreneurial orientation and internationalization with two TMT diversities found only in family firms: the family TMT ratio and generational involvement. An analysis of 191 Spanish family SMEs indicated that entrepreneurial orientation plays a significant role in explaining the degree of internationalization in family firms and that a diversely formed TMT shapes this relationship. A high concentration of family members in managerial positions hinders the international entrepreneurship process. This fact highlights the importance of hiring non-family managers to promote internationalization. The results also reveal that involving multiple generations in decision-making hampers entrepreneurial internationalization, generating control and coordination problems.     

Innovation management tools: implementing technology watch as a routine for adaptation

Innovation management (IM) is a multidisciplinary field which has been growing for the past few decades. However, the management of innovation is often considered equivalent to technology management or the management of research and development. By focusing on a set of small- and medium-sized enterprises operating in a medium-high-tech industry, the paper intends to determine the characteristics of IM tools. In particular, we address one of these tools, technology watch (TW), and define a set of generic stages to introduce the most relevant roles for its implementation. TW consists of the systematic observation, analysis and use of technological information, allowing companies to be aware of their external environment and learn from it. Through the implementation of TW processes, companies are able to assess and adapt their current technological base and the fit of their internal competences to the signals coming from the external environment.     

Millsian causation

The Directed Acyclic Graph (DAG) theory of causation is based on the assumption that randomly sampling the variables of a causal system will yield a joint probability distribution that satisfies the Markovian condition. It is shown here that this condition can be split into two parts, one of which is named the Millsian condition. It is further shown that the Millsian condition alone implies that causally unrelated sets of variables are conditionally independent given their common causes, very likely a key requirement stated by John Stuart Mill 150 years ago. In Millsian causation, unlike Markovian causation, it is possible for an indirect cause to be associated with its effect even when controlling for the intermediate direct causes. This phenomenon is explained by taking into account the existence of potential causal modulation.
