Stock prices, dividends, and structural changes in the long-term: The case of U.S.
2020
Abstract According to several empirical studies, the Present Value model fails to explain the behaviour of stock prices in the long-run. In this paper we consider the possibility that a linear cointegrated regression model with multiple structural changes would provide a better empirical description of the Present Value model of U.S. stock prices. Our methodology is based on instability tests recently proposed in Kejriwal and Perron (2008, 2010) as well as the cointegration tests developed in Arai and Kurozumi (2007) and Kejriwal (2008). The results obtained are consistent with the existence of linear cointegration between the log stock prices and the log dividends. However, our empirical r…
Integrated capital shares
2019
In empirical macroeconomics, inter-dependencies between countries are often analysed using cross-country correlations or graphical investigation of time series. This study shows that applying an alternative methodological approach - identification of common unobservable factors and using them as explanatory variables for country-specific time series - indicates a stronger cross-country integration of functional income distributions than the standard methods. The results vary only little between different samples, where both the country and year coverage change. Moreover, the main findings are not sensitive to the way capital depreciation is taken into account. The primary driving factor see…
- EL EFECTO FISHER Y LA PARIDAD DE INTERÉS REAL. EVIDENCIA PARA LA ECONOMÍA ESPAÑOLA
1999
This paper provides an empirical test of the Fisher effect and of the real interest parity. The objetive is to determinate the behavior of the ex-ante real interest that condicionate the intertemporal savings and investment decisions. The method used is the time series properties of the data, which allows to separate estimation of the long-run equilibrium relationship from the nuisance parameters that characterize the short-run dynamics. The results find support inthe long run for a tax-adjusted Fisher hypothesis but not for the real interest parity. En este trabajo se contrasta empíricamente el cumplimiento de la hipótesis de Fisher y de la paridad de interés real para el caso español. El …
Price and volatility dynamics between electricity and fuel costs: Some evidence for Spain
2012
Abstract The purpose of this study is to investigate the causal linkages between the Spanish electricity, Brent crude oil and Zeebrugge (Belgium) natural gas 1-month-ahead forward prices. Following Lutkepohl et al. (2004), we control for the presence of a structural change in the series and then we use the Johansen cointegration test and a vector error correction model (VECM) to embrace the analysis. Additionally, a multivariate generalized autoregressive conditional heteroskedastic (GARCH) model is applied to explore volatility interactions between the three markets involved in the study. Our findings reveal that Brent crude oil and Zeebrugge natural gas forward prices play a prominent rol…
Residual-based block bootstrap for cointegration testing
2010
We propose a new testing procedure to determine the rank of cointegration. This new method is based on the nonparametric resampling procedure, so-called Residual-Based Block Bootstrap (RBB), which is developed by Paparoditis and Politis (2003) in the context of unit root testing. Through Monte Carlo experiments we show that, in small samples, the RBB cointegration test has good power properties in relation to the other two well-known tests for cointegration, such as the Augmented Dickey–Fuller (ADF), applied to the residual of a cointegrating regression, and the Johansen's maximum eigenvalue tests. Likewise, this article looks at the influence played by the correlation of the ‘X’ variables …
Pricing of forwards and other derivatives in cointegrated commodity markets
2015
Abstract We analyze cointegration in commodity markets, and propose a parametric class of pricing measures which preserves cointegration for forward prices with fixed time to maturity. We present explicit expressions for the term structure of volatility and correlation in the context of our spot price models based on continuous-time autoregressive moving average dynamics for the stationary components. The term structures have many interesting shapes, and we provide some empirical evidence from refined oil future prices at NYMEX defending our modeling idea. Motivated from these results, we present a cointegrated forward price dynamics using the Heath–Jarrow–Morton approach. In this setting, …
Differentiated Integration and Disintegration in the EU after Brexit : Risks versus Opportunities
2019
Differentiation is becoming an increasingly salient feature of European integration. The multi‐faceted European crisis and the subsequent Brexit vote (paving the way for a ground‐breaking case of differentiated disintegration) have led scholars and practitioners to think about the consequences of differentiated integration. This article draws on five well‐established models of differentiation experienced by countries both inside and outside the Union: the EEA model; the Danish model of (quasi‐)permanent differentiation; the Swedish model of de facto differentiation; the instrumental model; and the British model of differentiated disintegration. It addresses the different risks and opportuni…
The determinants of social sustainability in work integration social enterprises: the effect of entrepreneurship
2021
Work integration social enterprises (WISEs) exist to fight poverty and social exclusion. They offer support and guidance to those at risk of exclusion to help these individuals join the labour market. This study examines the relationship between social enterprises (specifically, work integration social enterprises) and their social impact, considered here in the form of social sustainability. This article presents the results of empirical analysis of 62 Spanish work integration social enterprises using fuzzy-set qualitative comparative analysis. The article focuses on the entrepreneurial characteristics of the companies’ founders and managers as drivers of social value creation. Specificall…
Financial Integration and Fiscal Policy
2011
The aim of this paper is to assess the impact of financial integration on fiscal policy. Using an unbalanced panel of 31 OECD countries from 1970 to 2009, the paper shows that financial integration has significant disciplinary effects by reducing fiscal deficits and (discretionary) spending volatility. In addition, we find that financial integration affects the composition of government debt and enhances risk-sharing by increasing the share of foreign debt to the total. The results are robust to both de jure and de facto measures of financial integration, different measures of budget balance, and different estimation strategies.
Exploring Differentiated Disintegration in a Post-Brexit European Union
2019
In the aftermath of the British referendum to leave the European Union and the European Commission's ‘White Paper on the Future of Europe’, it is not only time to take stock of the existing literature on differentiated integration, but also to rethink the perimeters of disintegration. We argue that phenomena such as Brexit embrace forms of differentiation which trigger the need for conceptualizing differentiated disintegration altogether. This article first sketches the path of the scholarly debate in a chronological way to grasp the breadth of existing literature. Second, it discusses differentiated disintegration as a potentially new area for research. Mapping several scenarios for future…
