Determinantes do investimento privado : aplicação a Portugal

Abstract

A situação económica vivida desde o início do século, e em especial nos últimos dois anos em resultado da crise do subprime, tem-se reflectido também no investimento privado. Reconhecido o papel do investimento para o crescimento económico dos países, é fundamental que os Estados se preocupem em criar estratégias de incentivo. Para que as medidas sejam bem direccionadas, surge o presente trabalho que procura obter os determinantes do investimento privado em Portugal no período de 1985 a 2008. Tendo por base as principais teorias de investimento, foram seleccionadas e testadas algumas variáveis macroeconómicas. Para estimar a função de investimento para Portugal recorreu-se à metodologia dos Mínimos Quadrados Ordinários. De acordo com os resultados obtidos, as decisões de investimento do sector privado derivam positivamente da variação do produto, do investimento público e do índice de abertura comercial e negativamente do custo de capital (taxa de juro real) e da incerteza e instabilidade económica, reflectidas nas taxas de inflação e de desemprego. Neste sentido, é importante que o Governo português fomente o crescimento económico e reduza a instabilidade económica, de forma a que os agentes económicos sintam melhores expectativas relativamente ao futuro dos seus investimentos. Nesse sentido, a realização de investimentos públicos e um maior controlo sobre a taxa de desemprego revelam-se cruciais, bem como da taxa de inflação, embora esta seja uma competência do Banco Central Europeu. ABSTRACT: The economic situation since the beginning of the century, and especially in the last two years as a result of the subprime crisis, has been also reflected on private investment. Recognized the role of investment in economic growth of countries, it is essential that States be worry in creating incentive strategies. In order to measures are well targeted, the present work attempts to obtain the determinants of private investment in Portugal in the period 1985 to 2008. Based on the main theories of investment, some macroeconomics variables were selected and tested. To estimate the investment function for Portugal the methodology used was OLS. According to the results, the investment decisions of private sector derive positively from an increase of the product, public investment and trade liberalization and negative from cost of capital (real interest rate) and from uncertainty and macroeconomic instability, represent by the inflation and unemployment rates. Thus, it is important that the Portuguese Government encourages economic growth and reduce economic instability, so that economic agents feel better expectations for the future of their investments. In this sense, the realization of public investments and tight control over the rate of unemployment are crucial, as well as inflation rate, although this is a European Central Bank competence.
