The Cochrane-Orcutt procedure numerical examples of multiple admissible minima

We present two numerical examples of multiple admissible minima obtained by using the Cochrane-Orcutt iterative technique: a forgotten and somewhat farfetched example, constructed by Hildreth and Lu, and a new example, based on more typical economic data.     

Unconventional economic policies and sentiment: An international assessment

This paper estimates, using Bayesian and global VARs, the spillover effects of unconventional fiscal and monetary policies implemented in the United States and in the Eurozone during the last decade. Consumer confidence and investor sentiment indicators are introduced in the models in order to highlight the signalling channel in the responses to economic policy innovations in times of crisis. Our results reveal that consumer and investor perceptions of innovative economic measures are relevant to study the pass-through of economic policies to the real sector in times of crisis and zero lower bound interest rates. In particular, the signalling channel plays an important role in successful unconventional economic policies. Moreover, if unconventional economic policies have an impact abroad, the effects are similar to those measured in the domestic country/region. Consequently, coordination and transparency are a prerequisite for ensuring short-term growth after a global financial crisis.     

How integrated is the world economy?

This paper develops a methodology to measure the degree of economic integration between nations that are members of an integrated area. We show that a fully integrated economic area (IEA) is characterized by three properties regarding the distribution of member shares of total IEA output and total IEA stocks of physical and human capital. We then show that the expected distribution of member shares within a fully IEA is a harmonic series, with the share distribution depending only on the number of IEA members. This property is then used to develop a composite indicator of the degree of economic integration within an IEA that indicates the distance between the theoretical and actual distribution of shares: the closer is the actual distribution to the expected distribution, the greater the degree of integration. We empirically compute our degree of integration for US states, and alternative regional trading agreements (e.g., EU countries, MERCOSUR, Bangkok Agreement, etc.) and a “world” comprising 64 countries.
