A state’s right to prohibit unions from compelling employees to pay dues even when they are covered by a collective bargaining agreement has its basis in the 1947 Taft-Hartley amendments to the National Labor Relations Act (1935). After the amendment's passage, twelve (12) states passed...

Productivity and efficiency analyses have been indispensable tools for evaluating firms’ performance in the banking sector. In this context, the use of Artificial Neural Networks (ANNs) has been recently proposed in order to obtain a globally flexible functional form which is capable of...

This paper employs linear and nonlinear unit-root tests to investigate: a) the price dynamics of the home price indices included in the S&P/Case-Shiller Composite10 index, and b) the validity of the “ripple effect,” following the approach outlined in Meen (1999). In general, the findings...

This paper examines whether momentum drives the disposition effect and vice versa in the US stock market. The results from the analysis of the Fama-Macbethregressions show that the disposition effect drives momentum but not the other way around. Furthermore, we find that this relationship varies...

In this paper we propose exact likelihood-based mean-variance efficiency tests of the market portfolio in the context of Capital Asset Pricing Model (CAPM), allowing for a wide class of error distributions which include normality as a special case. These tests are developed in the framework of...

Macroeconomic time series often involve a threshold effect in their ARMA representation, and exhibit long memory features. In this paper we introduce a new class of threshold ARFIMA models to account for this. The threshold effect is introduced in the autoregressive and/or the fractional...

This paper proposes several statistical tests for finite state Markov games to examine the null hypothesis that the data are generated from a single equilibrium. We formulate tests of (i) the conditional choice probabilities, (ii) the steady-state distribution of states and (iii) the conditional...

This paper questions traditional approaches for testing the day-of-the-week effect on stock returns. We propose an alternative approach based on the closure test principle introduced by Marcus, Peritz and Gabriel (1976), which has become very popular in Biometrics and Medical Statistics. We test...
