Will smart machines do to humans what the internal combustion engine did to horses – make them obsolete? If so, can putting people out of work or, at least, good work leave them unable to buy what smart machines produce? Our model's answer is yes. Over time and under the right conditions,...

The 2015 Paris Accord is meant to control our planet's rising temperature. But it may be doing the opposite in gradually, rather than immediately reducing CO2 emissions. The Accord effectively tells dirty-energy producers to "use it or lose it." This may be accelerating their extraction and...

We investigate optimal consumption, asset accumulation and portfolio decisions in a realistically calibrated life-cycle model with flexible labor supply. Our framework allows for wage rate uncertainly, variable labor supply, social security benefits and portfolio choice over safe bonds and risky...

We develop a dynamic politico-economic theory of welfare state, featuring three groups of voters: skilled workers, unskilled workers, and old retirees. The welfare-state is modeled by a proportional tax on labor income to finance a demogrant in a balanced-budget manner to capture the essence of...

Foreign direct investment (FDI) is observed to be a predominant form of capital flows to emerging economies, especially when they are liquidity-constrained internationally during a global financial crisis. The financial aspects of FDI are the focus of the paper. We analyze the problem of...
