We investigate the empirical evidence on the Euler equation models using methods that are robust to weak instruments and structural changes for a set of eight countries. We start with the conventional closed economy model and consider extensions that include habits and hand-to-mouth consumers....

This paper studies rational bubbles in non-linear dynamic general equilibrium models of the macroeconomy. The term ‘Rational bubble' refers to multiple equilibria due to the absence of a transversality condition (TVC) for capital. The lack of TVC can be due to an OLG population structure. If a...

In his 2014 book, Thomas Piketty argues that wealth inequality is sharply increasing in r-g and refers to rg as ‘the central contradiction of capitalist economics', where r is asset returns and g is real income growth. To assess whether inequality is increasing in the (r-g)-gap this paper: 1)...

In this paper we propose a new indicator of monthly global real economic activity, named world steel production. We use world steel production, OECD industrial production index and Kilian's rea index to forecast world real GDP, and key commodity prices. We find that world steel production...

The rapid development of artificial intelligence (AI) is not only a scientific breakthrough but also impacts on human society and economy as well as the development of economics. Research on AI economics is new and growing fast, with a current focus on the productivity and employment effects of...

In modelling macroeconomic time series, often a monthly indicator of global real economic activity is used. We propose a new indicator, named World steel production, and compare it to other existing indicators, precisely the Kilian's index of global real economic activity and the index of OECD...

Cross-border capital flows are expected to lead to increased international risk sharing by facilitating borrowing and lending in global financial markets. This paper examines risk-sharing outcomes of various types of capital flows (foreign direct investment, portfolio equity, debt, remittance,...
