Essays on small open economy macroeconomics
AbstractThis thesis consists of an introductory chapter and three essays, all of which aim to study the functioning of a small open economy. The thesis starts with an investigation of export and import price determination and moves to a small open economy DSGE model framework in order to study the role of financial factors in economic fluctuations. In all three essays, theoretical small open economy models are used for quantitative analysis of the small open economy of Finland. The first essay develops a model for aggregate trade price inflation that takes into account two price setting conventions: local currency pricing (LCP) and producer currency pricing (PCP). In our empirical work, we confront our model with Finnish data and estimate the relative shares of LCP and PCP firms in the economy. In the estimation period 1980–1998, the share of local currency pricing was 40 percent in the export sector and 60 percent in the import sector, implying a limited pass-through from exchange rate to destination-country prices in both sectors. The second essay builds a small open economy DSGE model with the BGG financial accelerator and financial market shocks. In our empirical work covering the period 1995–2008, we provide evidence of an operative financial accelerator in Finland. The financial accelerator acts as an amplifying mechanism for many disturbances hitting the Finnish economy. Our main result is that financial market disturbances have contributed significantly to Finnish cyclical fluctuations between 1995 and 2008. Even allowing for several shocks stemming from both domestic sources and the international economy, domestic financial market shocks emerge as key drivers of recent business cycle fluctuations in Finland. The third essay studies the boom-bust period in Finland in the late 1980s and early 1990s, focusing on the role of financial factors and investment behaviour. We construct a small open economy DSGE model with the BGG financial accelerator and an unconventional shock structure that captures the key events of the episode. In this model framework, we study the role of financial market deregulation in the boom, the negative impact of the collapse of Soviet-Finnish trade in 1991, and the effect of the collapse of the fixed exchange rate regime in 1992. We argue that the financial accelerator mechanism is a key amplifying mechanism that helps the model to match, in particular, the large and persistent swings of investment first above and later below its trend. This essay demonstrates that the shocks Finland encountered combined with financial frictions are able to produce a boom and a severe depression, matching key salient features of the actual boom-bust cycle experienced in Finland in the late 1980s and early 1990s.
