The main purpose of this paper is to discern the dynamic causal relationships (in the Granger (temporal) sense) among sales, advertising and prices in the context of the Portuguese car market. The present research (based on multiple cointegration tests preceded by various unit root or non-stationarity tests) is one of the first attempts at putting the salesmarketing mix analysis within a multiv...

This paper deals with the question of how responsive farmers in SubSaharan Africa (SSA) are to changes in incentives. Employing Johansen's multivariate cointegration approach, it investigates for ten selected SSA countries the long-run effect of pricing policies, macroeconomic distortions, and certain non-price factors on agricultural production. It turns out that – in those cases where cointeg...

Bangladesh, a developing economy, contains trade deficit from her very inception. This paper makes an effort to understand the time series behavior of total export and total import of Bangladesh. Unit root tests recognize the existence of random walk in total export and total import time series. Johansen cointegration test reveals long-run equilibrium relationship between these two variables. G...

Structural VARs have been extensively used in empirical macroeconomics during the last two decades, particularly in analyses of monetary policy. Existing Bayesian procedures for structural VARs are at best confined to a severly limited handling of cointegration restrictions. This paper extends the Bayesian analysis of structural VARs to cover cointegrated processes with an arbitrary number of c...

This paper evaluates different strategies to forecast Spanish inflation using information of price series for 57 products and 18 regions in Spain. We consider vector equilibrium correction (VeqC) models that include cointegration relationships between Spanish prices and prices in the regions of Valencia, Andalusia, Madrid, Catalonia and the Basque Country. This approach is consistent with econo...

Coe and Helpman (1995) estimated a relationship between TFP and levels of domestic and foreign R&D capital, but couldn't provide compelling evidence of the panel eointegration needed to support their estimation strategy. This paper uses Pedroni's (1997, 1998) tests for panel cointegration in both the Coe-Helpman setup and in a framework with more cross-section heterogeneity. Criticisms of the C...

T he financial crisis that was started in the last months of 2008, spread out to all world countries in short-term and had broken out as public debt in the European Union and Euro area. Most affected countries from this financial crisis had been Portugal, Ireland, Italy, Greece, and Spain were named as PIIGS countries of Europe. The effect of public debt on economic growth had been a...
