We undertake a trade-growth accounting exercise by decomposing data on changes in bilateral international trade flows into their direct (endowment accumulation, productivity growth, changes in trade costs, changing preferences) and indirect components (general equilibrium effects). Furthermore,...

We challenge the common practice of estimating gravity equations with time-interval data in order to capture dynamic-adjustment effects to trade-policy changes. Instead, we point to a series of advantages of using consecutive-year data recognizing dynamic-adjustment effects. Our analysis reveals...

Recycling waste from used goods can substitute for scarce raw materials and reduce resource dependence. This paper presents a model of waste collection, recycling and final goods production using raw and recycled materials. Non-recycled waste must be safely stored by landfill to avoid...
