The Department for Transport in the United Kingdom has been a pioneer in including indirect benefits in the cost–benefit analysis of a transport project. They identify three types of wider impacts, i.e., (1) agglomeration, (2) increased or decreased output in imperfectly competitive markets,...

The Henry George Theorem (HGT) states that, in first-best economies, the fiscal surplus of a city government that finances the Pigouvian subsidies for agglomeration externalities and the costs of local public goods by a 100% tax on land is zero at optimal city sizes. We extend the HGT to...

Many sources of urban agglomeration involve departures from the first-best world. The benefit evaluation of a transportation project must then take into account agglomeration benefits along with any direct user benefits. Using a monopolistic competition model of differentiated intermediate...

We generalize the formulae for welfare changes by Arkolakis, Costinot, and Rodríguez-Clare (2012) and Melitz and Redding (2014a) to allow for various cardinalizations of the subutility functions for varieties. Despite the same macro restrictions and the same equilibrium allocations, our new...

Many sources of urban agglomeration, such as the gains from variety, bette rmatching, and knowledge creation and diffusion, involve departures from the first-best world. Benefit evaluation of a transportation project must then take into account changes in excess burden along with any direct user...

Mobile money service in Uganda has expanded rapidly, penetrating as much as over 30 percent of the adult population in just four years since its inception. We investigate the impact of this financial innovation on household welfare, using household survey panel data from rural Uganda. Results...

Japan’s outstanding debt keeps increasing and there are concerns regarding its sustainability. Nevertheless, the financial market seems to be neglecting such concern. Its growing debt level and subdued general price level are not easy to explain from the fiscal theory of price level (FTPL)...

We analyze the economic impact on key sectors of a compound disaster in Taiwan. While Taiwan has high-tech export-oriented industries such as semiconductors and electronic products, three out of four nuclear power plants are located in the at-risk areas close to its capital city with industrial...

Experiments with family groups are rare, but since many decisions are taken at the household level or occur within the household it is an important area to investigate. I discuss some of the methodological challenges involved in doing experiments with couples and families and consider major...

Forward guidance or more specifically policy duration commitment invented and developed by the Bank of Japan has become an essential part of unconventional monetary policy instruments employed by modern central banks. This paper’s simple empirical analysis finds that the market believes or...
