Transport development and the evolution of economic geography

In this paper, based on the recent advances in the new economic geography (e.g., Fujita et al. [12]), we analyze impacts of transport costs on the spatial patterns of economic agglomeration. We first identify prototypes from the existing models, and explain the mechanism of how transport costs influence the balance between economic forces of agglomeration and dispersion. We then investigate the transformation of the agglomeration/dispersion patterns given gradually decreasing transport costs for different goods.Received: Received: July 2004 / Accepted: January 2005, Accepted: Received: July 2004 / Accepted: January 2005, JEL Classification: R12Tomoya Mori: Correspondence toThe authors are grateful to David Bernstein, Tatsuo Hatta, Komei Sasaki, Tony E.

DESTABILIZING EFFECTS ON INCOME ADJUSTMENT PROCESS WITH FISCAL POLICY LAGS

Since a finite time delay in government purchases of goods and service cannot be ignored, this paper studies how such a time lag in a fiscal policy affects the stability of the income adjustment process. Formulating the income adjustment process with time delay, it adopts two different approaches: one is a fixed time lag and the other is a continuously distributed lag. It is demonstrated that the continuously distributed time lag has the stronger destabilizing effect if the adjustment of the government expenditure is slow while the fixed lag has the stronger destabilizing effect if this adjustment is rapid.     

Is silence golden? An empirical analysis of firms that stop giving quarterly earnings guidance

We investigate firms that stop providing earnings guidance (“stoppers”) either by publicly announcing their decision (“announcers”) or doing so quietly (“quiet stoppers”). Relative to firms that continue guiding, stoppers have poorer prior performance, more uncertain operating environments, and fewer informed investors. Announcers commit to non-disclosure because they (i) do not expect to report future good news or (ii) have lower incentives to guide due to the presence of long-term investors. The three-day return around the announcement is negative. Stoppers subsequently experience increases in analyst forecast dispersion and decreases in forecast accuracy but no change in return volatility or analyst following.     

Rates of Return on Art Objects, the Fisher Hypothesis, and Inflationary Expectations

After surveying the evolution of the major methodologies in inflation hedging, this study presents a unique methodology that uses principal component factor analysis to separate the effects of variability in the real rate of return from the nominal rate of return. This approach allows the effects of both anticipated and unanticipated inflation on rates of return to be estimated more precisely. This study finds that art objects perform well in terms of average real rates of return and that the market, though not perfect, integrates anticipated inflation into the rates of return. However, unanticipated inflation is very often negatively related to the rates of return.

Mobile money,risk sharing,and educational investment: Panel evidence from rural Uganda

We examine the impact of the rapidly expanding mobile banking service “mobile money” on rural households' ability to smooth investment in schooling after a negative shock. We find that a negative shock induces a 9.3‐percentage point decrease in per school‐age child educational expenditure for households who do not use mobile money compared to an 8.3‐percentage point decrease for households that have adopted mobile money. The underlying mechanism is an increase in remittance receipt and the diversity of senders owing to the reduction in transactions cost provided by mobile money. We show that our results are robust to alternative mechanisms. We use the expansion in mobile money agent network as an exogenous variation in access to mobile money.     

Capital-tax financing and scale economies in public-input production

Contrary to the dominant view of inefficient tax competition, Oates and Schwab (1991) show that capital-tax financing of public inputs leads to efficiency when the supply of these inputs is conditioned on business investment (Oates, W.E., Schwab, R.M., 1991. The allocative and distributive implications of local fiscal competition). This paper demonstrates that the cost structure of public-input production is relevant to their proposition on efficient capital-tax financing. That proposition holds if the per-unit cost of public inputs is exogenously fixed; however, it does not hold if public-input production exhibits scale economies. Also, this paper compares our analysis with the Zodrow-Mieszkowski model. That comparison illustrates the importance of the way public inputs are rationed to private firms.     

Entry in tax competition: a note

This paper extends the tax competition analysis of public inputs to the case where the number of regions that compete for business investment is endogenous. To determine the number of competing regions, a fixed cost of regional development is introduced into the Zodrow–Mieszkowski model of public-input provision. It is shown that allowing for region entry does not affect the analytical results of inefficient public-input provision under tax competition. This paper also shows that the equilibrium number of competing regions is inefficient.
