Do firms share the same functional form of their growth rate distribution? A statistical test
2014
We introduce a new statistical test of the hypothesis that a balanced panel of firms have the same growth rate distribution or, more generally, that they share the same functional form of growth rate distribution. We applied the test to European Union and US publicly quoted manufacturing firms data, considering functional forms belonging to the Subbotin family of distributions. While our hypotheses are rejected for the vast majority of sets at the sector level, we cannot rejected them at the subsector level, indicating that homogenous panels of firms could be described by a common functional form of growth rate distribution.
Learning competitive pricing strategies by multi-agent reinforcement learning
2003
Abstract In electronic marketplaces automated and dynamic pricing is becoming increasingly popular. Agents that perform this task can improve themselves by learning from past observations, possibly using reinforcement learning techniques. Co-learning of several adaptive agents against each other may lead to unforeseen results and increasingly dynamic behavior of the market. In this article we shed some light on price developments arising from a simple price adaptation strategy. Furthermore, we examine several adaptive pricing strategies and their learning behavior in a co-learning scenario with different levels of competition. Q-learning manages to learn best-reply strategies well, but is e…
Why is equity order flow so persistent?
2015
Abstract Order flow in equity markets is remarkably persistent in the sense that order signs (to buy or sell) are positively autocorrelated out to time lags of tens of thousands of orders, corresponding to many days. Two possible explanations are herding, corresponding to positive correlation in the behavior of different investors, or order splitting, corresponding to positive autocorrelation in the behavior of single investors. We investigate this using order flow data from the London Stock Exchange for which we have membership identifiers. By formulating models for herding and order splitting, as well as models for brokerage choice, we are able to overcome the distortion introduced by bro…
How does learning affect market liquidity? A simulation analysis of a double-auction financial market with portfolio traders
2007
We study the relationship between liquidity and prices in an artificial financial market where portfolio traders with limited resources interact through a continuous, electronic open book. We depart from the standard asset pricing framework in two ways. First, we assume that investors have incomplete information about the distribution of returns. Second, we model the portfolio choice problem using prospect-type preferences. We model the utility function in terms of deviations of the portfolio growth rate from a specified target growth rate, and we assume that investors are more sensitive to downside movements. We show that the parameters defining the learning process affect the price dynami…
Variable selection in the analysis of energy consumption-growth nexus
2015
There is abundant empirical literature that focuses on whether energy consumption is a critical driver of economic growth. The evolution of this literature has largely consisted of attempts to solve the problems and answer the criticisms arising from earlier studies. One of the most common criticisms is that previous work concentrates on the bivariate relationship, energy consumption–economic growth. Many authors try to overcome this critique using control variables. However, the choice of these variables has been ad hoc, made according to the subjective economic rationale of the authors. Our contribution to this literature is to apply a robust probabilistic model to select the explanatory …
Are the determinants of CO2 emissions converging among OECD countries?
2013
This paper studies convergence in CO2emission intensity (CO2 emissions over GDP) among OECD countries over the period 1960-2008 based on its determinants, namely, energy intensity (energy consumption over GDP) and the so-called carbonisation index (CO2 emissions over energy consumption). We apply the Phillips and Sul (2007) methodology, which tests for the existence of convergence clubs. Our results highlight that differences in emission intensity convergence are more determined by differences in convergence of the carbonisation index rather than by differences in the dynamic convergence of energy intensity.
Gobiernos locales y política de fomento de las cooperativas y la economía social: entre canal de transmisión de la política multinivel y agente proac…
2022
Este trabajo analiza el papel desempeñado en la actualidad por los gobiernos locales de la Comunitat Valenciana en materia de fomento del cooperativismo y la economía social. Además de ofrecer información empírica al respecto, para la región valenciana de España, valorando el grado de implicación de los poderes públicos locales, los tipos de políticas desplegados, los factores limitantes en su despliegue y las características comunes de los municipios más activos, se ha analizado el papel sistémico de estos gobiernos locales desde un doble rol, el de ser un canal de transmisión, desde la perspectiva multinivel, de la política de economía social promovida desde niveles supramunicipales, en p…
Household optimism and overborrowing
2018
We use Finnish household-level data from 1994 to 2013 to measure how often and what kind of forecast errors households make and how the errors are linked to the households' borrowing behavior and overindebtedness. We find that those households that make the largest optimistic forecast errors have greater debt-to-income ratios. They also are more likely to report that they suffer from excessive debt loads and have problems in coping with their bills. There are no such systematic effects for the households that make pessimistic forecast errors. peerReviewed
The euro area sovereign debt crisis: Can contagion spread from the periphery to the core?
2014
Abstract We examine the determinants of joint default risk of euro area countries during 2007–2011. To accomplish this, we recover joint default probabilities from individual CDS contracts. In contrast to earlier theoretical studies, we find that financial linkages are an active contagion transmission channel only in the case of the troubled periphery euro area economies. During the current sovereign debt crisis, real economy linkages play a more important role in transmitting shocks from the euro area periphery towards its core. Countries that have stronger trade interconnections with troubled economies tend to have a higher expected joint default risk.
Sector-based corporate citizenship
2010
This paper approaches the much-debated issue of corporate citizenship (CC). Many models depict the development process of CC, and yet attempts to find one extensive definition remain in progress. We argue that more than one type of citizenship may be needed to fully describe the concept. So far, social factors have dominated the definitions of CC, but citizenship functions can also be found in other areas. In fact, for maximum benefit, the type of citizenship should be tied to the sector and business field of the corporation in question. Using data drawn from three internationally operating corporations headquartered in Finland, we introduce three different types of CC that are in line with…
