In this paper, we use simulated data to investigate the power of different causality tests in a two-dimensional vector autoregressive (VAR) model. The data are presented in a non-linear environment that is modelled using a logistic smooth transition autoregressive (LSTAR) function. We use both...

For testing unit root in single time series, most tests concentrate on the time domain. Recently, Fan and Gençay (Econom Theory 26:1305–1331, <CitationRef CitationID="CR8">2010</CitationRef>) proposed a wavelet ratio test which took advantage of the information from the frequency domain by using a wavelet spectrum methodology. This...</citationref>

In this paper, we use the wavelet technique to improve the over-rejection problem of the traditional Dickey-Fuller test for unit root when the data suffers from GARCH (1,1) effect. The logic is based on that the wavelet spectrum decomposition can separate out information of different frequencies...

In this paper, we propose a Nonlinear Dickey-Fuller F test for unit root against first order Logistic Smooth Transition Autoregressive LSTAR (1) model with time as the transition variable. The Nonlinear Dickey-Fuller F test statistic is established under the null hypothesis of random walk...

In innovation analysis the logit model used to be applied on available data when the dependent variables are dichotomous. Since most of the economic variables are correlated between each other practitioners often meet the problem of multicollinearity. This paper introduces a shrinkage estimator...

We investigate the importance of ethnic origin and local labour markets conditions for self-employment propensities in Sweden. In line with previous research we find differences in the self-employment rate between different immigrant groups as well as between different immigrant cohorts. We use...

This paper studies the impact of remittances on investment. Workers’ remittances to developing countries have grown to be an important source of financing, amounting to around $300 billion a year. The funds are used for both consumption and investment in the home countries of the migrants. The...

This paper employs a time series cointegration approach to evaluate the relationship between manufacturing firm failure and macroeconomic factors for the Swedish manufacturing sector in the period 1986 – 2006. It uses quarterly data for this period. We found that in long run a firms’ failure...
