Essays on investment, debt and macroeconomic dynamicsDissertation Advisor
Willi SemmlerDissertation Abstract
Chapter 1 studies empirically how relative supply and demand conditions on the capital market aﬀected US ﬁrm-level investment over the business cycles from 1977 to 2011. A dynamic econometric speciﬁcation of capital accumulation including sales growth, Tobin’s q, the cash ﬂow-capital ratio and the cost of capital as covariates is ﬁtted by a rolling window System GMM estimator using quarterly data on publicly traded US corporations in order to obtain time-varying coeﬃcients. I ﬁnd that the investment eﬀects of the variables capturing the demand-side of the capital market, i.e. sales growth and Tobin’s q, behave counter-cyclically, whereas this does not hold for the investment eﬀects of supply-side variables such as cash ﬂow or the cost of capital. The results suggest that investment was typically driven by adverse demand rather than supply conditions on the capital
market during the most severe recessions.
Chapter 2 studies the sustainability of sovereign debt in 15 OECD countries from 1980 to 2010with a focus on how and in what countries debt sustainability changed after the commencement of the Euro Convergence Criteria in 1997 as well as after the ﬁnancial meltdown in 2007. Sustainability is defined as the validity of the inter-temporal budget constraint of the government and a suﬃcient condition is tested using single-country and pooled regressions. While the yield spreads suggest the debt crisis is a problem of the southern Euro countries, I ﬁnd a lack of debt sustainability for Greece, Portugal and France but not for Italy and Spain. The crisis adversely aﬀected sustainability primarily in stand-alone countries rather than in members of the European Monetary Union. The results support the view that countries within a monetary union are more prone to investors’ sentiments than stand-alone countries.
Within a framework of an aggregative macro model with instantaneous output adjustment, chapter 3 reconciles Harrodian instability and a constant long-run utilization rate with the principle of eﬀective demand by endogenizing the capacity output-capital ratio. Its change over time is argued to be a positive function of the utilization rate. As stabilizing forces, distribution and debt dynamics are considered. I argue that with plausible non-linearities in the investment function limit cycles consistent with empirical observations for the US can be generated by the model with reasonable parameter values and functional forms. With an endogenous capacity-capital ratio the paradox of thrift as well as the paradox of cost may hold despite a constant long-run utilization rate.
