This paper considers VAR/VECM models for variables exhibiting cointegration and common features in the transitory components. While the presence of cointegration reduces the rank of the long-run multiplier matrix, other types of common features lead to rank reduction in the short-run dynamics. These common transitory components arise when linear combination of the first differenced variables in...

A positive technology shock may lead to a rise or a fall in per capita hours, depending on how hours enter the empirical VAR model. We provide evidence that, independent of how hours enter the VAR, a positive technology shock leads to a weak response in nominal wage inflation, a modest decline in price inflation, and a modest rise in the real wage in the short-run and a permanent rise in the lo...

the non-differentiability and implicit definition of boundary of production possibility set (pps) in data envelopment analysis (dea) are two important difficulties for obtaining directional characteristics, including different elasticity measures and marginal rates of substitution. also, imposing weight restrictions in dea models have some shortcomings and misunderstandings. in this paper we ut...

This paper investigates the long-run and short-run linkages between insurance activity and banking credit for G-7 countries. To minimize the pretest bias and overcome the structural changes, we adopt the bootstrap Granger causality test applied to full sample and subsamples with a fixed window size. The Johansen cointegration test with GMM-IV estimator finds a long-run positive relation between...

The recent literature on taxation and growth has stressed the optimality of a zero long-run taxation on all accumulative factors of production. For a given path of government spending, the optimal tax plan requires the government to build up a positive stock of public wealth in the short run in the long-run, government spending can be financed with the income accruing from the management of the...

Theoretical predictions and empirical evidence on the impact of foreign aid and fiscal policy on growth are mixed. This paper examines the effect of fiscal variables (government expenditure and revenue) and aid on growth using annual time series data for Kenya over the period 1964 – 2002. Multivariate cointegration (VAR) and vector error correction models (VECM) are estimated to establish both ...

6 Data assimilation obtains improved estimates of the state of a physical system by com7 bining imperfect model results with sparse and noisy observations of reality. In the four 8 dimensional variational (4D-Var) framework data assimilation is formulated as an opti9 mization problem, which is solved using gradient based optimization methods.The 4D10 Var gradient is obtained by forcing the adjo...

Duration dependent Markov-switching VAR (from now on DDMSVAR) models are time series models with data generating process consisting in a mixture of two VAR processes, which switches according to a two-state Markov chain with transition probabilities depending on how long the process has been in a state. Interesting applications of this class of models have been carried out in business cycle ana...

This chapter reviews the literature on the econometric relationship between DSGE and VAR models from the point of view of estimation and model validation. The mapping between DSGE and VAR models is broken down into three stages: 1) from DSGE to statespace model; 2) from state-space model to VAR(1); 3) from VAR(1) to nite order VAR. The focus is on discussing what can go wrong at each step of th...
