The relative popularity of adjustable-rate mortgages (ARMs) and fixed-rate mort- gages (FRMs) varies considerably both across countries and over time. We ask how movements in current and expected future interest rates affect the share of ARMs in total mortgage issuance. Using a nine-country...

Environmental Engel curves (EECs) plot the relationship between households' incomes and the pollution embodied in the goods and services they consume. They provide a basis for estimating the degree to which observed environmental improvements, which come in part from changing consumption...

Improving end-use energy efficiency--that is, the energy-efficiency of individuals, households, and firms as they consume energy--is often cited as an important element in efforts to reduce greenhouse-gas (GHG) emissions. Arguments for improving energy efficiency usually rely on the idea that...

Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between "dirty" (internal combustion engine) and "clean" (e.g. electric and hybrid) patents across 80 countries over several decades. We show that...

We analyze alternative policies such as a disposal content fee, a subsidy for recyclable designs, unit pricing of household disposal, a deposit-refund system, and a manufacturer `take-back' requirement. In order to identify the problem being addressed, we build a simple general equilibrium model...

Two centuries of Greek debt crises highlight the pitfalls of relying on external financing. Since its independence in 1829, the Greek government has defaulted four times on its external creditors - with striking historical parallels. Each crisis is preceded by a period of heavy borrowing from...

We document that in semiformal economies, banks lend to tax-evading individuals based on the bank's assessment of the individual's true income. This observation leads to a novel approach to estimate tax evasion. We use microdata on household credit from a Greek bank, and replicate the bank...
