Development Of An Econometric Model Case Study: Romanian Classification System

2015

Abstract The purpose of the paper is to illustrate an econometric model used to predict the lean meat content in pig carcasses, based on the muscle thickness and back fat thickness measured by the means of an optical probe (OptiGrade PRO).The analysis goes through all steps involved in the development of the model: statement of theory, specification of the mathematical model, sampling and collection of data, estimation of the parameters of the chosen econometric model, tests of the hypothesis derived from the model and prediction equations. The data have been in a controlled experiment conducted by the Romanian Carcass Classification Commission in 2007. The purpose of the experiment was to …

Dealing with spatial data pooled over time in statistical models

2012

Recent developments in spatial econometrics have been devoted to spatio-temporal data and how spatial panel data structure should be modeled. Little effort has been devoted to the way one must deal with spatial data pooled over time. This paper presents the characteristics of spatial data pooled over time and proposes a simple way to take into account unidirectional temporal effect as well as multidirectional spatial effect in the estimation process. An empirical example, using data on 25,357 single family homes sold in Lucas County, OH (USA), between 1993 and 1998 (available in the MatLab library), is used to illustrate the potential of the approach proposed.

Production Function Estimation in Stata Using the Ackerberg–Caves–Frazer Method

2016

We present a new e-class command, acfest, that implements the method of Ackerberg, Caves, and Frazer (2015, Econometrica 83: 2411–2451) to estimate production functions. This method deals with the functional dependence problems that may arise in the methods proposed by Olley and Pakes (1996, Econometrica 64: 1263–1297) and, particularly, Levinsohn and Petrin (2003, Review of Economic Studies 70: 317–341) (implemented in Stata by Yasar, Raciborski, and Poi [2008, Stata Journal 8: 221–231] and Petrin, Poi, and Levinsohn [2004, Stata Journal 4: 113–123], respectively). In particular, the acfest command yields (nonlinear, robust) generalized method of moments estimates using a Mata function an…

Who cares? Evidence on informal and formal home care use in Estonia

2019

Despite increasing attention to long-term care (LTC) and related challenges in the Estonian social policy agenda, the distributional fairness of LTC services in the country has received very limited attention. Using SHARE data, we address informal and formal home care services and identify the socio-economic factors that drive or hinder their use among the Estonian elderly. The relationship between informal and formal home care utilization is estimated applying the new approach to instrumental variable method proposed by Lewbel [2012. Using heteroscedasticity to identify and estimate mismeasured and endogenous regressor models. Journal of Business and Economic Statistics, 30(1), 67–80]. We …

EUGENICS AND SOCIALIST THOUGHT IN THE PROGRESSIVE ERA: THE CASE OF JAMES MEDBERY MACKAYE

2018

The aim of this essay is to assess James Medbery MacKaye’s contribution to socialist thought during the Progressive Era. Largely forgotten today, MacKaye proposed a special version of socialism, which he called “Pantocracy,” based on a peculiar blend of utilitarian and eugenic assumptions. Specifically, MacKaye held that biological fitness mapped to the capacity for happiness—biologically superior individuals possess a greater capacity for happiness—and saw the eugenic breeding of “a being or race of beings capable in the first place of happiness” as a possibility open by the advent of Pantocracy. Incidentally, this essay provides further evidence that the influence of eugenic and racialist…

Le commerce équitable et la société civile internationale : une chance pour la mondialisation d'un droit de l'économie solidaire

2003

SUMMARY The international trade law passes through a crisis of legitimacy following the inequitable character of its rules and the irrelevance of its principles to the peculiarities of the North-South relations. Being the legal translation of the capitalist free market economic system, these rules are to protect the mercantile and free trade values. In order to overcome this crisis the movement of fair trade has emerged and has since its origin been supported by members of the international civil society. Fair trade means taking into account the standard of living and the conditions of employment of the marginalized producers in developing countries so as to improve them. This study is an a…

Mothers’ non-standard working and childcare-related challenges : A comparison between lone and coupled mothers

2016

Purpose – The purpose of this paper is to particularly focus on lone-mother families, comparing the childcare-related challenges experienced by working lone mothers and coupled mothers in three European countries in the context of a 24/7 economy and non-standard working hours (e.g. evening, night and weekend work). Design/methodology/approach – This study utilises survey data from Finnish, Dutch and British working mothers (n=1,106) collected as part of the “Families 24/7” research project. Multivariate regression analysis is used to analyse the associations between childcare-related challenges, maternal non-standard working, lone motherhood and country of residence. Findings – The results…

Forecasting Exchange Rates Volatilities Using Artificial Neural Networks

2000

This paper employs Artificial Neural Networks to forecast volatilities of the exchange rates of six currencies against the Spanish peseta. First, we propose to use ANN as an alternative to parametric volatility models, then, we employ them as an aggregation procedure to build hybrid models. Though we do not find a systematic superiority of ANN, our results suggest that they are an interesting alternative to classical parametric volatility models.

Time-Varying Fundamentals of the Euro–Dollar Exchange Rate

2006

Abstract This study examines changes in the impact of the economic fundamentals on the euro–dollar exchange rate. First, the monetary model is augmented with the equity markets and the model is estimated in its structural form. Second, the time-varying impacts of the long-run fundamentals representing equilibrium in different markets on the euro–dollar exchange rate are examined using Kalman filtering. The time-varying structural model indicated that the relative importance of the different fundamentals was not equal and the impact of the fundamentals was time-dependent.
