The domestic Chilean wine market is examined through the estimation of an error correction model allowing for structural breaks in the cointegrating vector. Our findings support both parameter instability and one structural break in the long-run relationship in 1982. The wine demand becomes more...

This paper investigates possible changes in Chilean domestic consumer preferences for wine through the estimation of a demand function that allows for structural breaks and regime shifts in the cointegrating relationship. Our findings support both higher own-price elasticity and higher...

Quinoa has evolved considerably in the past decades, becoming consolidated as a fundamental pillar for Andean farming communities and emerging as a prominent actor in the global superfood market. Despite this, prices of this grain have been characterized by complex dynamics, with substantial...

We consider the problem of testing for a structural break in the spatial lag parameter in a panel model (spatial autoregressive). We propose a likelihood ratio test of the null hypothesis of no break against the alternative hypothesis of a single break. The limiting distribution of the test is...

This paper reviews the recent trends in agricultural investments (both public and private) and tries to find structural breaks in the trends over the period of 1960-2017. Comparing the growth performance of investments and farm output (GDPAg and production) in various sub-periods based on...

From time to time, economies undergo far-reaching structural changes. In this paper we investigate the consequences of structural breaks in the factor loadings for the specification and estimation of factor models based on principal components and suggest test procedures for structural breaks....

This paper shows that the parsimoniously time-varying methodology of Callot and Kristensen (2015) can be applied to factor models. We apply this method to study macroeconomic instability in the US from 1959:1 to 2006:4 with a particular focus on the Great Moderation. Models with parsimoniously...

This paper identifies and characterizes episodes of structural change in the 27 years that preceded the Great Recession. This is done by performing Bai-Perron (2003a, 2003b) tests on 61,843 time series that span 34 countries, which collectively accounted for 81% of Gross World Product in 2013....

Motivated by the need to avoid possible parameter bias associated with previous works, we examined the impacts of private sector credit on economic growth in Nigeria using the Gregory and Hansen (1996) cointegration test that accounted for structural breaks and endogeneity problems. The method...

This paper proposes a parsimoniously time varying parameter vector autoregressive model (with exogenous variables, VARX) and studies the properties of the Lasso and adaptive Lasso as estimators of this model. The parameters of the model are assumed to follow parsimonious random walks, where...
