In markets where production has adverse externalities, policy makers may wish to increase welfare by imposing a cap on market entries. In this paper, we examine the implications that the cap has on the firms' investment equilibrium policy and on social welfare in the presence of market...

This paper considers investments in cost-reducing technology in the context of contributions to climate protection. Contributions to mitigating climate change are analyzed in a two-period model where later contributions can be based on better information, but delaying the contribution to the...

This paper argues that the usual framing of discussions of money, monetary policy, and fiscal policy plays into the hands of conservatives.That framing is also largely consistent with the conventional view of the economy and of society more generally. To put it the way that economists usually...

We examine how basic research should be financed. While basic research is a public good benefiting innovating entrepreneurs it also affects the entire economy: occupational choices of potential entrepreneurs, wages of workers, dividends to shareholders, and aggregate output. We show that the...

What shapes the optimal degree of progressivity of the tax and transfer system? On the one hand, a progressive tax system can counteract inequality in initial conditions and substitute for imperfect private insurance against idiosyncratic earnings risk. At the same time, progressivity reduces...

We present a model of transnational terrorism where two countries, home and foreign, face a terrorist threat based in the foreign country. The home country chooses how much to invest in defending itself or in reducing terrorist resources either indirectly by subsidising the foreign country or by...

The gap between willingness-to-pay (WTP) and willingness-to-accept (WTA) benefit values typifies situations in which reference points — and direction of movement from reference points — are consequential. Why WTA-WTP discrepancies arise is not well understood. We generalize models of...

This paper proposes an operationally simple and easily generalizable methodology to incorporate climate change damage uncertainty into Integrated Assessment Models (IAMs). Uncertainty is transformed into a risk-premium, damage-correction, region-specific factor by extracting damage distribution...

Dealers, who strategically supply liquidity to traders, are subject to both liquidity and adverse selection costs. While liquidity costs can be mitigated through inter-dealer trading, individual dealers' private motives to acquire information compromise inter-dealer market liquidity. Post-trade...
