Functional Linear Regression
2018
This article presents a selected bibliography on functional linear regression (FLR) and highlights the key contributions from both applied and theoretical points of view. It first defines FLR in the case of a scalar response and shows how its modelization can also be extended to the case of a functional response. It then considers two kinds of estimation procedures for this slope parameter: projection-based estimators in which regularization is performed through dimension reduction, such as functional principal component regression, and penalized least squares estimators that take into account a penalized least squares minimization problem. The article proceeds by discussing the main asympt…
Back-Propagation Artificial Neural Network for ERP Adoption Cost Estimation
2011
Published version of a chapter in the book: Enterprise information systems, vol 220, part 2, 180-187. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-24355-4_19 Small and medium size enterprises (SMEs) are greatly affected by cost escalations and overruns Reliable cost factors estimation and management is a key for the success of Enterprise Resource Planning (ERP) systems adoptions in enterprises generally and SMEs specifically. This research area is still immature and needs a considerable amount of research to seek solid and realistic cost factors estimation. Majority of research in this area targets the enhancement of estimates calculated by COCOMO family models.…
The Effects of IFRS Adoption on the Unconditional Conservatism of Spanish Listed Companies
2017
This paper analyses the effects on unconditional conservatism of the mandatory adoption of International Financial Reporting Standards (IFRS) by Spanish listed companies in January 2005. The lack of robustness in the previous evidence justifies analysing this issue from different perspectives. To this end, we use, for the first time in this context, Ahmed and Duellman’s methodology (J. Account. Econ., 2007). In its design, these authors consider the impact of growth options and other future incomes, controlling for the idiosyncratic factors that the literature has found to condition this type of conservatism. Additionally, beyond the pooled regression techniques usually used, we use econome…
Estimation of urban structural flood damages: the case study of Palermo
2000
Abstract The estimation of flood damage is a fundamental step in the economic analysis of a flood control projects. In particular, frequency–damage functions, derived from the hydrologic, hydraulic and damage relationships, are one of the fundamental pieces of information upon which expenditure decisions are based. The aim of this study has been to develop an empirical frequency–damage relationship, obtained by means of detailed local studies, which could be a judgement tool for flood mitigation measures in strongly urbanised drainage areas. Monuments and other estates having a cultural or artistic significance have been specifically taken into account. The analysis has been carried out for…
Heterogeneous Firms, Globalisation and the Distance Puzzle
2015
Despite the strong pace of globalisation, the distance effect on trade is persistent or even growing over time (Disdier and Head, 2008). To solve this distance puzzle, we use the recently developed gravity equation estimator from Helpman et al. (2008) (HMR henceforth). Using three different data sets, we find that the distance coefficient increases over time when ordinary least squares (OLS) is used, while the non-linear estimation of HMR leads to a decline in the distance coefficient over time. The distance puzzle, thus, arises from a growing bias of OLS estimates. The latter is explained by an increase in the importance of the bias from omitting the number of heterogeneous exporting firms…
Implicit public debt thresholds: An operational proposal
2020
Abstract Gauging the public debt-to-GDP ratio a country can sustain in the medium-run without putting fiscal sustainability at risk is a question of key relevance for policy-makers. Deviations from a safe level of debt should be watched over in order to take corrective measures. In this paper we make a proposal for an operational characterization of the “prudent debt level”. To do so, we use standard methods based on Vector Autoregressions to compute the probability that the public debt ratio exceeds a given threshold, using the Spanish case as an example. The resulting probabilities are highly and positively correlated with market risk assessment, measured by the spread with respect to the…
Effectiveness of Private and Public High Schools: Evidence from Finland
2019
Abstract A number of papers have compared the effectiveness of private and public schools in different institutional settings. However, most of these studies are observational and do not utilize experimental or quasi-experimental design to evaluate the value-added or the effectiveness of private schools in comparison to public schools. This study focuses on private and public high schools in Helsinki, the capital city of Finland. We use two different methods to compare private and public schools, value-added estimation and regression discontinuity design (RDD). Although based on somewhat different assumptions, both methods allow us to evaluate the causal effect of private schools on the exi…
Do nonreciprocal preferential trade agreements increase beneficiaries' exports?
2014
Abstract This paper investigates whether and to what extent nonreciprocal preferential trade agreements (NRPTAs) have increased developing countries' exports to richer countries. Using recent developments in the econometric analysis of the gravity equation over the period 1960–2008, we find robust evidence that, on the whole, NRPTAs and the Generalized System of Preferences have had an economically significant effect on exports from developing countries. However, the estimation of catch-all dummies masks heterogeneous results for the individual programs.
Estudio de la insolvencia empresarial en las cooperativas mediante técnicas multivariantes
2020
One of the consequences of the current economic crisis is a significant rise in business failures, which is fueling the interest of researchers and users for its analysis, review and update of the traditional models.In reviewing the financial literature on business failure in our country, we noticed that the are very few studies focusing exclusively on cooperative enterprises, although this kind of companies have a broad presence in our country. This significant lack of studies on this kind of business, the recent availability of large databases and the current economic circumstances have influenced us to undertake this work. The main paper objective focuses on the estimation of appropriate…
Testing for financial contagion between developed and emerging markets during the 1997 East Asian crisis
2005
In this paper we examine whether during the 1997 East Asian crisis there was any contagion from the four largest economies in the region (Thailand, Indonesia, Korea and Malaysia) to a number of developed countries (Japan, UK, Germany and France). Following Forbes and Rigobon, we test for contagion as a significant positive shift in the correlation between asset returns, taking into account heteroscedasticity and endogeneity bias. Furthermore, we improve on earlier empirical studies by carrying out a full sample test of the stability of the system that relies on more plausible (over) identifying restrictions. The estimation results provide some evidence of contagion, in particular from Japan…
