A few signatures matter: Barriers to entry in Italian local politics

Competition for public office is an essential feature of democracy but having many candidates competing for the same position might lead to voter confusion and be counterproductive. In current democracies, ballot access regulations limit citizens’ right to become candidates, seeking to balance this trade-off by discouraging frivolous contenders. This paper examines the causal effect of signature requirements – a widespread ballot access regulation – and finds that their impact goes beyond this goal. I use data on Italian local elections and apply a regression discontinuity design (RDD) to estimate the effects of these requirements on electoral competition, candidates’ selection, voter participation and administrative efficiency. I find that signature requirements reduce the number of candidates running for office, decrease electoral competition, lead to a more experienced pool of candidates, and reduce voter turnout. The positive effects of this policy are observed in municipalities with fragmented political systems, where signature requirements lead to fewer wasted votes and fewer spoiler candidates. The downside is observed in municipalities with concentrated political systems: signature requirements increase the frequency of uncontested races and reduce voter participation. Findings reveal how this barrier to entry impacts key dimensions of democracy and indicate that designing efficient electoral institutions requires a clear understanding of local political contexts.     

ON THE DETERMINANTS OF LOCAL TAX RATES: NEW EVIDENCE FROM SPAIN

This article examines the determinants of local tax rates. For the two main local taxes in Spain—the property tax and the motor vehicle tax—we test the existence of tax mimicking, yardstick competition, and political trends in a sample of 2,713 municipalities. Using various spatial models, the results support the hypothesis of tax mimicking, with coefficients above 0.40. We also show the relevance of political variables such as the ideology of incumbents and political fragmentation. The fact that incumbents with weaker political support exhibit stronger mimicking behavior is interpreted as evidence in favor of yardstick competition. Finally, we find that incumbents mimic neighboring municipalities ruled by the same political party, confirming the political trends hypothesis. (JEL C31, H71, H77)     

Price setting and the steady-state effects of inflation

This paper examines how price setting plays a key role in explaining the steady-state effects of inflation in a monopolistic competition economy with transactions-facilitating money. Three pricing variants (optimal prices, indexed prices, and unchanged prices) are introduced through a generalization of the Calvo-type setting that allows price indexation. We found that in an economy with less indexed prices, the steady-state negative impact of inflation on output is higher. Regarding welfare analysis, our results support a long-run monetary policy aimed at price stability with a close-to-zero inflation target. This finding is robust to any price setting scenario.JEL Classification: E13, E31, E50The writing of this paper commenced during the time I spent on the Research Visitors Programme 2001 of the European Central Bank and an earlier version of the paper became ECB Working Paper No. 140.

McCallum, Frank Smets, and Oscar Bajo-Rubio for their valuable comments and suggestions, and the Ministerio de Ciencia y Tecnología of Spain for its financial support (Research Project 2002/00954).     

Can a decline in search cost increase prices?

This paper provides a new explanation of why a decline in consumers’ price search cost may not lead to lower prices. In a duopoly with price competition, I show that when some consumers are captive to one firm, there may be a non‐monotonic relationship between search cost and market power; firms may charge high prices with higher probability and the average price charged may be higher when consumers’ price search cost falls below a critical level. Furthermore, when firms have asymmetric captive segments, expected prices charged by each firm may move in opposite directions as search cost declines.     

Is there a quality bias in the Canadian CPI? Evidence from microdata

Rising consumer prices may reflect shifts by consumers to new higher‐priced products, mostly for durable and semi‐durable goods. I apply Bils’ (2009) methodology to newly available Canadian consumer price data for non‐shelter goods and services to estimate how price increases can be divided between quality growth and price inflation. I find that less than one third of observed price increases during model changeovers should be attributed to quality growth. This implies overall price inflation close to inflation measured by the official index. I conclude that, according to Bils’ methodology, the quality bias is not an important source of potential mismeasurement of CPI inflation in Canada.     

Election frequency,choice fatigue,and voter turnout

Influential scholars have argued that frequent elections lead to voter fatigue and can therefore be directly responsible for low turnout in countries characterized by frequent contests. However, other theories predict that frequent elections can even increase turnout. The existing empirical evidence is problematic as it simply correlates election frequency with turnout. By contrast, I exploit a natural experiment in the German state of Hesse, where voters from different municipalities faced the same electoral contest but experienced different election frequency, due to the staggered timing of some local elections. I find that when two elections are scheduled within a relatively short period of time, voter turnout at the later election is significantly reduced. This effect is stronger when the election is deemed less important in the eyes of the voters. Election frequency thus might also partly explain the wide turnout gap between first- and second-order elections, as suggested by Lijphart (1997).     

Vertical Control and Price Cycles in Gasoline Retailing

We examine Norwegian gasoline pump prices using daily station‐specific observations from 2003 to 2006. The four big gasoline companies use a vertical restraint that is adopted industry‐wide (labeled price support). This moves price control from the hands of independent retailers into the hands of the headquarters. Retail gasoline prices follow a fixed weekly pattern, where we observe de facto simultaneous decision‐making by the headquarters (without knowledge of their rivals’ prices) when every Monday around noon they decide to increase pump prices to the same level. The price level on Mondays corresponds to the recommended prices published by the headquarters of the gasoline companies.     

THE RELATIONSHIP BETWEEN ILLEGAL DRUG PRICES AT THE RETAIL USER AND SELLER LEVELS

This article uses 1985–2000 DEA data on marijuana and cocaine prices in various metropolitan areas to empirically test two contrasting theories of the relationship between illegal drug prices at the retail seller and user levels. Regression results overwhelmingly reject a multiplicative model in which the ratio of prices at the two levels is constant, but strongly support an additive model in which the difference between these prices is constant. This finding reduces the attractiveness of policies aimed at raising wholesale prices, because retail price responses, and thus potential drug demand deterrence, would be substantially smaller than commonly assumed.

Purchasing Power Parity When Prices Are I(2)

This paper examines the purchasing power parity (PPP) hypothesis over the modern float using data on 15 OECD currencies. Evidence is presented that suggests the price levels evolve as second-difference stationary processes, i.e., integrated of order two ( P₁– I (2)). A necessary condition for PPP when prices are I (2) is that prices are cointegrated across countries to an I (1) relative price. In general this relative price is not the same as the simple price ratio. For some of the relationships examined, this relative price level is cointegrated with the exchange rate, implying a long-run equilibrium between nominal exchange rates and prices.     

Price of High‐quality Daycare and Female Employment

Using local variation between municipalities, I analyze the degree to which the price of high‐quality publicly subsidized childcare affects female employment following maternity leave. Importantly, prices are income dependent and thus likely endogenous, yet by exploiting information on minimum income compensation during non‐employment, I bypass this problem. The results show that the price negatively affects employment. A price increase of €1 per month decreases employment by 0.08%, which corresponds to a price elasticity of −0.17. These effects prevail during the first 12 months after childbirth. I also find that availability of childcare increases employment.     

Price as a quality signal in a strategic competition context: The role of a disclosure law

This paper analyses a firm's incentive to use price as a signal of quality in a duopoly competition, even though she can credibly and costlessly disclose her true quality. When a firm sets a higher price to signal higher quality, it has strategic effects on the price chosen by her rival. This could result in higher equilibrium prices and profits. Hence, a mandatory disclosure law is useful to prevent the practice of using of higher price as a device to signal higher quality, and in turn equilibrium prices would be lower. From a welfarist point of view, this argument justifies the establishment of such disclosure law.JEL Classification: D43, D82, K29I would like to thank Dolors Berga, Nicolas Boccard, Ramon Caminal, Carmen Matutes, José Luis Moraga and Ricard Torres for their useful comments.

国际农产品价格如何影响了中国农产品价格?

本文使用月度数据考察国际农产品价格是否影响中国农产品价格,以及影响程度和可能的影响机制。在控制了其他影响因素的条件下,本文证实了国际农产品价格对国内价格具有经济意义上的显著影响,各种农产品的国内价格对相同产品国际价格的反应程度存在较大差异,玉米、大米和大豆价格的国际价格弹性介于0.20到0.36之间,小麦的国际价格弹性为0.05左右,国内外农产品市场间高度的整合关系主要是通过国际贸易建立的。中国在未来为保持粮价稳定需要加大对农业的扶持力度,加强国内农产品储备,合理地对农产品贸易进行管制,建立农产品价格预警机制,并通过财政补贴等手段平抑因国际价格波动而带来的国内农产品价格上涨。     

Local public expenditure in Sweden a model where the median voter is not necessarily decisive

This paper deals with local public expenditures, and the analysis is based on cross-section data for the Swedish municipalities. Two models are estimated; one is the basic median voter model where the decisive voter is assumed to be the voter with median income, while the other is a more general statistical alternative. The statistical alternative nests the basic median voter model as a special case, which makes it easy to test the null hypothesis that the basic median voter model is the correct model, given that the alternative is the true general structure. Although our results indicate a rejection of the null hypothesis, the estimation results are, nevertheless, similar for the two models.     

The import price index with trade barriers: theory and evidence

The standard economic import price index hinges on an assumption of free trade. Applying the index to situations with barriers to trade yields biased results compared to a true import price index. To circumvent this problem, it is common to use average prices, such as unit values, as an aggregator function. However, the use of average prices is not rooted in economic theory. In this paper, I generalise the economic import price index to allow for barriers to trade in the form of quantity constraints. To illustrate the theoretical framework, I use the case of imports of textiles to Norway from 1988 to 1997. I find that a standard economic import price index, such as the Laspeyres index, grossly overstates import costs and that this bias is significantly reduced by using unit values.     

On volatility of prices in arbitrage-free markets

Summary This paper addresses the question of what one can learn about the dynamics of an economy from observing cross-sectional and time series variations in the volatility of prices in an arbitrage-free securities market. We introduce the notions of stochastic derivatives, marginal risk-adjusted growth rates, and marginal risk exposure in a single factor economy. We show that future variations in the state of the economy are due to two independent sources: the marginal risk-adjusted growth rate and the changes in marginal risk exposure. Using the martingale characterization of arbitrage-free prices, together with a martingale representation formula due to Haussmann (1978), we show that cross sectional variations in price volatility of assets with linear payoffs can be used to identify the sum of these two sources. Measurements of price volatility for assets with linear payoffs are not sufficient for complete identification of the independent determinants of possible future variations in the economy. However, using the volatility of prices of options on the state variable, we can identify the stochastic derivative and hence compute the price volatility of any path independent contingent claim.I am grateful to David Kreps and Kenneth Singleton for helpful conversations and to an anonymous referee for useful remarks.

Demand and distance: Evidence on cross-border shopping

An important issue for commodity taxation is the extent to which changes in foreign taxes affect the extent of cross-border shopping and thereby, domestic tax revenue. We use data from Swedish municipalities to estimate how responsive alcohol sales are to foreign prices, and relate the sensitivity to the location’s distance to the border. Typical results suggest that the elasticity with respect to the foreign price is around 0.3 in the border region; moving 150 (400) km inland reduces the cross-price elasticity to 0.2 (0.1). Our estimates suggest that a recent Danish cut in the spirits tax reduced Swedish tax revenues from spirits sales by more than 2%, and that an attempt by Sweden to cut taxes in response would reduce tax revenues further.     

Hazardous Waste Hits Hollywood: Superfund and Housing Prices in Los Angeles

This paper contributes to the ongoing debate concerning the effect of various actions taken by the U.S. Environmental Protection Agency under CERCLA, commonly known as the Superfund Program, on housing prices. This study uses a housing transaction panel dataset encompassing the five major counties of the Los Angeles Combined Statistical Area to estimate the program’s influence on the local housing market. Using house and time-varying census tract fixed effects, I am able to avoid many of the endogeneity problems seen in previous research attempting to measure the Superfund treatment effect. An estimate of the effect on housing prices is given for each of the major events that occur under a typical Superfund remediation. After controlling for confounding correlated unobservables, I find a 7.3 % increase in sales price for houses within 3 km of a site that moves through the complete Superfund program. The analysis gives evidence of positive price appreciation for housing markets and serves as a lower bound for measuring remediation benefits.     

Do neighboring municipalities matter in industrial location decisions? Empirical evidence from Spain

This paper focuses on industrial location, assuming that entrepreneurs not only consider the advantages associated with a certain municipality, but also those coming from nearby areas. Exploratory analysis reflects the existence of spatial patterns in the creation of manufacturing establishments and sheds light on the geographical scope on which agglomeration economies operate in industrial location. Spatial Probit models and standard Probit models with spatially lagged explanatory variables are estimated to test whether neighboring municipalities’ location decisions and characteristics, including agglomeration economies, matter in industrial location choices. Results show that neighboring municipalities location decisions and characteristics help to explain location decisions of new establishments for 11 manufacturing industries in Spanish municipalities (NUTS V) over the period 1991–1995.     

Bubbles in UK house prices: evidence from ESTR models

Recent movements in stock and house prices have led to an examination of the presence of bubbles. Whilst, there is extensive research on stock price data, there is relatively less for house prices. This paper uses a present‐value model for house prices to test for the presence of bubbles. The results support the presence of a non‐fundamental component within UK national and regional house prices. In particular, for the majority of series considered, evidence is presented of linear non‐stationarity within the fundamental present‐value relationship, and of non‐linear stationarity, implying the presence of a non‐fundamental, or bubble, component. Furthermore, evidence is presented that prices adjust quicker when they are below fundamental equilibrium, than when they are above fundamental equilibrium, i.e. there is downward price stickiness. These results support the hypothesis that house price dynamics can be characterised by price‐to‐price momentum. Finally, forecast evidence suggests that real prices are likely to adjust downwards and converge with fundamental value.
