The determinants of an economy's balanced growth path for income per capita may vary over time. In this paper we apply unobserved components analysis to an otherwise standard panel model of economic growth dynamics so that an economy's long run relative income per capita can change at any point...

Immigration has been a significant part of US population growth over recent decades, with the number of ``foreign born to non-US nationals" rising from approximately 10 million in 1970 to nearly 40 million or 12.9% of the US total population in 2010. In this paper, using a VAR with sign...

Why has the recent covid-19 pandemic led to the imposition of export quotas in many countries? Why is the agricultural sector highly protected in developed economies? We show how the addition of subsistence constraints to the standard models of international trade together with a potential shock...

Should immigration be regarded as an exogenous shock? If so, what is its effect on native wages? Might any effect differ across different sectors of the economy? In this paper we answer these questions by applying macroeconomic time series methods to a time series of UK labor market variables...
