Why Investors Should not be Cautious about the Academic Approach to Testing for Stock Market Anomalies
2005
The ability of investors to implement seasonal strategies implied by academic papers has been widely criticized, most recently by Hudson et al. (Applied Financial Economics, 12, 681–86, 2002). This paper addresses these concerns, and provides an example of a strategy derived from academic papers that indicates how and to what profitability such a strategy can be implemented. In particular, the pre-holiday anomaly is examined, where returns tend to be higher on the day before a holiday. After checking that the pre-holiday return compensates market frictions, the existence and the changing nature of such anomaly is tested. Finally, the profitability of the pre-holiday trading strategy in an o…
Measuring consumers’ level of satisfaction for online food shopping during COVID-19 in Italy using POSETs
2021
Abstract The pandemic COVID 19 has upset the economic, social, financial, and general behavioral systems. Global crisis has a large impact overall and related fallouts significantly affect existent structural paradigms in every country and region across the world. In particular, the spread of COVID-19 pandemic has led to having to rethink the way we produce and consume food. Within this global change, a rise in the number of consumers who purchase food products online in order to comply with the rules aimed at limiting the circulation of the virus should be emphasized. Consequently, probably causing a long-term positive effect on m-commerce. The purpose is to elaborate on the index of the s…
Measuring well-being in Colombian departments. The role of geography and demography
2021
This paper provides a composite indicator of well-being for the 33 Colombian departments in the year 2016. The indicator is built by adapting the well-known OECD Better Life Index to the regional level, and includes the dimensions of income, health, education, safety, housing, environment, labour market, and civic engagement and governance. As to the methodology, Data Envelopment Analysis and Multi-Criteria Decision-Making techniques are employed, an approach which enables a comparison of well-being across departments and the construction of rankings. The results yield several take-away messages. First, there are substantial disparities in well-being across Colombian departments. Second, de…
The internationalization of family businesses: A review of extant research
2010
Abstract Among family businesses (FBs) internationalization has become a strategy for growth, and sometimes even for survival. This review article presents an analysis conducted on 25 refereed journal articles on FB internationalization. The articles typically portrayed the internationalization of FBs as a sequential process following the Uppsala model of internationalization; by contrast, some FBs were regarded as “born-again” global firms. In methodological terms, most of the articles focused on what-questions rather than why/how-questions. The articles did not make much use of internationalization or FB-specific theories. Our study takes a step towards clarifying the following issues: (i…

Macroeconomic Impact of Pension System Upon Private Pension Funds Scheme. Empirical Evidence from Central and Eastern European Countries
2021
Abstract The significance of retirement savings and private pension funds increased in the latest decades and gathered important amounts of capitals. The purpose of this paper is to investigate the macroeconomic effects of pension systems from an investment perspective in five Central and Eastern European countries. The analyzing process regarding several underlying macroeconomic effects of pension systems started from the premises that there is a strong connection between the structure of pension systems, the national economy and the development of the financial sector. The econometric tests were processed and applied by using pool data regression models and the method Pooled Instrumental …
More firms, more competition? The case of the fourth operator in France's mobile phone market
2010
Accepted, Forthcoming; International audience; To foster competition the French government authorized a fourth operator, ‘Free', to enter the country's mobile phone market at the end of 2009 alongside Orange, SFR and Bouygues Telecom (BT), who held respectively one-half, one-third and one-sixth of the market. By using a stylized model of France's phone market, we have examined what we call the regulator's nightmares and dreams. If Cournot competition is in place before Free's entry, minimizing the total profit fails to maximize the consumer surplus and the total surplus; the maximum most realistic price fall is 6.7% compared to three-way competition and could be 1.7% only; if Orange, SFR an…
A naïve approach to speed up portfolio optimization problem using a multiobjective genetic algorithm
2012
a b s t r a c t Genetic algorithms (GAs) are appropriate when investors have the objective of obtaining mean-variance (VaR) efficient frontier as minimising VaR leads to non-convex and non-differential risk-return optimisation problems. However GAs are a time-consuming optimisation technique. In this paper, we propose to use a naive approach consisting of using samples split by quartile of risk to obtain complete efficient frontiers in a reasonable computation time. Our results show that using reduced problems which only consider a quartile of the assets allow us to explore the efficient frontier for a large range of risk values. In particular, the third quartile allows us to obtain efficie…
The asset reallocation channel of quantitative easing. The case of the UK
2022
We investigate the impact of the Bank of England's asset purchase program (APP) on the composition of assets of UK banks with unique data on the received reserves injections. The Monetary Policy Committee (MPC) didn't expect there to be strong transmission of the APP's impact through the bank lending channel. We find that compared to the control group, treated banks reallocated their assets towards lower risk-weighted investments, such as government se-curities, but did not provide more credit to the real economy. Overall, our findings suggest that when banks are not adequately capitalised, risk-based capital constraints can limit the effec-tiveness of expansionary unconventional monetary p…
The path of R&D efficiency over time
2015
Abstract In this paper we investigate the pattern of R&D efficiency in terms of the number of product innovations achieved by firms over time. Using a panel dataset of Spanish manufacturing firms for the period 1990–2006, we follow the innovative performance of R&D active firms and observe that innovation rates change over firms' R&D histories. To explain these facts we propose a model that explicitly acknowledges the twofold composition of firms' R&D expenditures, comprising spending on both physical capital for R&D projects and payments to researchers. We regard this latter component of R&D as a source for dynamic returns to firms' R&D investments. Consequently firms' innovation outcomes …
