Conditional heteroskedasticity is a common feature of financial and macroeconomic time series data. When such data are used to estimate dynamic regression models, standard checks for serial correlation are inappropriate. In such circumstances, it is obviously important to have valid tests that are reliable in finite samples. Generalizations of the standard Lagrange multiplier test and a Hausman...

THE "Syndrome de Balado" (Balado and Satanowsky, 1929), later known as chiasmal arachnoiditis (Ch.A.) has been reported by many authors (Cushing, 1930a, b; Heuer and Vail, 1931; Craig and Lille, 1931; Vincent, Puech, and David, 1931; David, Hartmann, and Hebert, 1936; Bollack, David, and Puech, 1937a; Hausman, 1937; Vail, 1938). Its aetiology and pathogenesis have, however, remained controversi...

This paper investigates spatial panel data models with spatially and serially correlated disturbances. We …rst discuss the short panels and consider their estimation by both …xed e¤ects and random e¤ects speci…cations. With a between equation properly de…ned, the di¤erence of the random vs. …xed e¤ects models can be highlighted. We show that the random e¤ects estimate is a pooling of the within...

The design of a website interface plays an important role in online purchasing, and customers are more likely to visit and buy from betterdesigned websites. However, previous studies have not provided consistent information about the features a website should provide. Based on Hausman and Siekpe’s (2009) comprehensive model, this study aims to empirically verify whether the model can be applied...

This paper first identifies the determinants of income satisfaction of individuals within the household and, secondly, characterises whether their preferences are altruistic or egoistic. To that end, it formulates a theoretical framework from the collective family model whose stochastic formulations are estimated for 14 EU countries by using the eight waves of the European Community Household P...

This paper analyzes the effect of ICT infrastructure availability on FDI inflow in D8countries (Bangladesh, Indonesia, Iran, Egypt, Nigeria, Malaysia, Pakistan and Turkey). Panel data for period 1997-2018 has been used analysis done using fix model suggested by Hausman specification test. The result shows positive significant between inflows, along with other controlling variables like market s...

In this paper we consider the efficient instrumental variables estimation of a panel data model with heterogeneity in slopes as well as intercepts. Using a panel of U.S. airlines, we apply our methodology to a frontier production function with cross-sectional and temporal variation in levels of technical efficiency. Our approach allows us to estimate time-varying efficiency levels for individua...

This paper gives a test of overidentifying restrictions that is robust to many instruments and heteroskedasticity. It is based on a jackknife version of the overidentifying test statistic. Correct asymptotic critical values are derived for this statistic when the number of instruments grows large, at a rate up to the sample size. It is also shown that the test is valid when the number instrumen...

In this paper we relate university licensing revenues to both university research expenditures and characteristics of the university and the university technology transfer office. We apply the Hausman–Taylor estimator for panel data with time-invariant explanatory variables and the Arellano–Bover dynamic panel model to unbalanced panels for the years 1991–2003 and balanced panels for the years ...

In a recent comment, David Albouy claims that the data series we constructed for European settler mortality in Acemoglu, Johnson and Robinson (2001) suffers from “inconsistencies, questionable judgements, and errors.” He proposes two series, for “barracks” and “campaigns,” that he claims are better measures of settler mortality, and shows his recodings weaken or eliminate the first-stage relati...
