nÃo hà / The objective of this work is to identify whether the Wagner Law, which refers to the effect of public spending on economic growth can be observed for the Brazilian reality. According to Wagner, the public sector is able to intervene in the economy to alter its growth trajectory, with such a process promoted by higher expenses. To test the hypothesis Wagner information was collected on the amount of government spending and the Brazilian production between 1909 and 2012, extracted from IPEADATA. The processing of information in order to reproduce the arguments that led to the completion of the verification or not the Wagner Law was based on techniques of time series. The model of Vector Autoregressive (VAR), the analysis of Granger and Cointegration test were used. Still, the tests of Dickey - Fuller and Phillip - Perron test for identification to check the type of behavior that characterizes the best series of public spending and growth were used. The results highlight that both variables have decided not stationary in level, you characterize as well as a process I(1). The impulse response functions showed a positive relationship not spending towards growth and a low explanatory power of the fluctuations of the latter after the first 20 periods, respectively. The test of Granger pointed out that there is a unidirectional relationship between public spending and growth, with the same expenditure towards growth - ie, only growth can affect the spending behavior in the Granger sense. Finally, the cointegration analysis did find arguments in favor of a long-term relationship for the series in question. / O objetivo deste trabalho à identificar se a lei de Wagner, que se remete ao efeito dos gastos pÃblicos sobre o crescimento econÃmico, pode ser observada para a realidade brasileira. Segundo Wagner, o setor pÃblico à capaz de intervir na economia de modo a alterar sua trajetÃria de crescimento, sendo tal processo promovido pela elevaÃÃo das despesas. Para testar a hipÃtese de Wagner foram coletadas informaÃÃes sobre o montante de gastos governamentais e sobre a produÃÃo brasileira entre 1909 e 2012, extraÃdas do IPEADATA. O processamento das informaÃÃes de modo a reproduzir argumentos que levaram a conclusÃo sobre a verificaÃÃo ou nÃo da lei de Wagner foram baseado em tÃcnicas de sÃries temporais. Foram utilizados o modelo de Vetores Auto-Regressivos (VAR), a anÃlise de causalidade de Granger e o teste de CointegraÃÃo. Ainda, foram utilizados os testes de Dickey-Fuller Aumentado e o teste de Phillip-Perron para identificaÃÃo para verificaÃÃo do tipo de comportamento que melhor caracteriza as sÃries do gasto pÃblico e do crescimento. Os resultados destacam que ambas as variÃveis apresentam-se de forma nÃo estacionÃria em nÃvel, caracterizas, assim, como um processo I(1). As funÃÃes de impulso respostas evidenciaram uma relaÃÃo nÃo positiva do gasto para com o crescimento e um baixo poder de explicaÃÃo das flutuaÃÃes desta Ãltima pela primeira apÃs 20 perÃodos, respectivamente. O teste de Granger destacou que existe uma relaÃÃo unidirecional entre gasto pÃblico e crescimento, sendo a mesmo no sentido crescimento-gasto, ou seja, somente o crescimento à capaz de afetar o comportamento dos gastos no sentido de Granger. Por fim, a anÃlise de cointegraÃÃo encontrou argumentos em favor de uma relaÃÃo de longo prazo para as sÃries em questÃo.

This study investigates the validity of the twin deficits hypothesis for the Turkish quarterly data over the 1988:1-2005:2 periods. To this end, we consider a VAR variable space containing budget deficits, current account deficits, real output, real interest rates and real exchange rates and employ cointegration, equilibrium/error correction mechanism techniques along with Granger-non-causality tests and impulse response analyses. The empirical results from decompositions of the budget and current account deficits into their cyclical and structural components suggest that both CAD and BD are counter-cyclical. The twin deficit hypothesis, consistent with the conventional Mundell-Flemming framework, postulates that current account and budget deficits move together in the long run and the causality runs from the former to the latter. The results from Engle-Granger and Johansen cointegration procedures support either the twin divergence or the Ricardian equivalence postulations but not the twin deficits hypothesis. Current account deficits and budget deficits are also found to be jointly endogenous. The short-run impacts of budget deficits on current account deficits are found to be mainly through the real exchange rate and real interest rate channels.
