INTERNATIONAL DEVIATIONS FROM THE LAW OF ONE PRICE: THE ROLE OF SEARCH FRICTIONS AND MARKET SHARE*

This article examines the size and persistence of international deviations from the law of one price in an industry with search frictions. Cost differences lead foreign and domestic firms to price differently within countries. When local firms are more common in each country, there are large and persistent price differences across countries. Large and persistent changes in international relative costs lead to large and persistent changes in international relative prices. Dynamic considerations imply that the amount of a cost shock firms pass through to prices is U‐shaped in the market share of firms receiving the shock.     

The law of one price revisited: How do goods market frictions generate large and volatile price deviations?

This paper analyzes the role of goods market frictions in accounting for the large and volatile deviations from the Law of One Price (LOP) in a framework of flexible prices. We draw a distinction between the goods market frictions that are required to consume tradable goods (e.g., distribution costs) and those that are necessary for international transactions (e.g., trade costs). We find that trade costs generate LOP deviations by introducing a no-arbitrage band, while distribution costs cause the price to deviate from the LOP by affecting the probability that trade will occur, given the band. We then conduct a Monte Carlo simulation to show that real exchange rate volatility is positively associated with trade costs, but negatively related to distribution costs. This effect depends on the interplay of trade costs and distribution costs, as they work in opposite directions when creating arbitrage opportunities.     

The law of one price: conditional convergence evidence from disaggregated data

This article contributes to the literature on the Law of One Price (LOP) and absolute Purchasing Power Parity (PPP) in two ways. First, it uses a novel set of PPP data from the International Comparison Programme for OECD countries and 195 internationally comparable products from 1980 to 1996. Second, it derives and applies a test of conditional σ-convergence, which does not require long-time spans or high frequency data. Between 1990 and 1996 for 10 out of 23 countries, a significant reduction in the variance of the deviations from LOP is found for tradeables, but none in case of nontradeables. For the former, the deviations from LOP close out at half-lives between 2.2 and 6.3 years. However, there are also persistent country-specific deviations from LOP parities.     

RAMSEY TAXES MEET PRICE RIGIDITY

‘Ramsey taxes’ are commodity taxes that minimize deadweight loss. Evidence has shown dramatic differences in the extent of price rigidity across goods: while the prices of some goods change frequently, the prices of other goods seldom change. This paper examines Ramsey taxes in the presence of heterogeneous price rigidity. We find that, to minimize deadweight loss, lower (higher) tax rates should be imposed on goods with rigid prices if their relative prices are too high (low) relative to the would‐be situation of no price stickiness. Intuitively, Ramsey taxes remedy the relative price distortion caused by the price rigidity of some goods. We calibrate our model to data from Taiwan and the USA, showing a significant cut in welfare cost if Ramsey rather than uniform taxes are applied.     

PRICE DISPERSION,INFLATION, AND WELFARE*

We examine the implications of inflation for both price dispersion and welfare in a monetary search economy. In our economy, if the degree of buyers' incomplete information about prices is fixed, both price dispersion and real prices are increasing in inflation. As the inflation rate approaches the Friedman rule, both price dispersion and welfare losses vanish. If households choose the number of prices to observe, then the optimal inflation rate may exceed the Friedman rule as inflation induces search and, up to a point, raises welfare by eroding market power.     

MARKET POWER,PRICE ADJUSTMENT,AND INFLATION*

We study a monetary search economy in which endogenous fluctuations in market power driven by changes in consumers' search intensity determine the extent of price adjustment to movements in productivity and the money growth rate. A calibrated version of the economy exhibits countercyclical fluctuations in markups and is consistent with the observed incomplete response of nominal prices to cost movements associated with productivity fluctuations and to changes in the money growth rate. Furthermore, a higher average rate of inflation results in a lower average markup and increases the sensitivity of prices to fluctuations in either productivity or money growth.     

Monetary Shocks and Real Exchange Rate Dynamics: a Reappraisal

This paper proposes a two‐country general‐equilibrium model incorporating a tradable sector with pricing‐to‐market as well as a nontradable sector. In that case, real exchange rate fluctuations arise from two sources: changes in the relative price of traded goods, that exemplify deviations from the law of one price, and movements in the relative price of traded to nontraded goods across countries. Our framework sheds light on the propagation mechanisms through which monetary shocks affect the real exchange rate. More specifically, the two components respond in opposite directions to monetary disturbances, which is consistent with data. Besides, the introduction of nontraded goods does not alter the predictive power of monetary shocks because the presence of nontraded goods magnifies the response of the deviation from the law of one price.     

PRICE DYNAMICS WITH CUSTOMER MARKETS

Using microdata from a U.S. retailer we document that customer turnover responds to pricing. We study the optimal price setting of a firm when its demand has an extensive margin that is elastic to price due to customers' opportunity to search for an alternative supplier. The price pass‐through of idiosyncratic productivity shocks is incomplete, with the most productive firms passing through more. Firm demand is more persistent than price. Higher demand is associated with lower markups due to higher search intensity, despite flexible prices. We find empirical support for these predictions in microdata from the retail industry.     

THE PRICE LEVEL, THE QUANTITY THEORY OF MONEY, AND THE FISCAL THEORY OF THE PRICE LEVEL

This paper examines price‐level determination from the perspective of portfolio choice. Arbitrages among money balances, bonds, and investment goods determine their relative demands. Returns to real balance holdings and after‐tax returns to investment goods determine the relative values of nominal and real assets. Because expectations of government policies ultimately determine the expected returns to both nominal and real assets, the price level depends on interactions among current and expected future monetary and fiscal policies. The quantity theory and the fiscal theory emerge as special cases produced by restricting both the margins and the policies considered.     

PRICE ANALYSIS AND A SYSTEM OF PRICE STATISTICS

For some considerable time the interest in price statistics has mainly been focused on their use as "intermediate goods". The requirements of a system of price index numbers which have to be established in this connection are largely in the field of statistical coordination (integration of statistics on quantities, values and prices).
Recently the inflation problem has given rise to an increased interest in price statistics as "final goods". A meaningful analysis of inflation will devote attention to the relation between input prices and output prices. In this article several versions of an analysis of prices of final demand categories based on an ordinary Leontief input-output scheme are presented and the needs for price statistics are discussed. In fact a self-contained system of price statistics emerges from the price analysis.
There is a difference in the nature of the price index numbers required in compiling input-output tables in constant prices (Paasche) and that in the case of price analysis (Laspeyres). However the need for price observation runs largely parallel because in both cases the same detailed information on price developments will probably be used.
Price analysis gives the possibility of a step-by-step approach in building up a system of price index numbers.     

Pricing in Segmented Markets, Arbitrage Barriers, and the Law of One Price: Evidence from the European Car Market

The paper uses micro‐level price data from the European car market to examine why there are deviations from the law of one price. The absolute law of one price is strongly rejected, but there is convergence to its relative version. Two sets of explanations are considered: (i) price‐setting in segmented markets, and (ii) arbitrage barriers. Overall, the determinants of arbitrage costs have more explanatory power. The single most important factor is the distance between markets. Evidence for Belgium and Luxembourg suggests that a single currency lowers price differences significantly.     

QUANTITY AND PRICE INDEXES FOR CONSTRUCTION

Construction has traditionally constituted one of the problem areas in the preparation of industry price and quantity statistm with in the system of national accounts of most countries. The difficulty stems from what is considered to be the unique character of construction projects. This has unnecessarily impeded the calculation of output price indexes and has resulted in the use of various input-based prices as proxies for output prices. One of the objectives of the development of the system of construction price statistics described in this paper is to permit deflation of the outputs of construction industries in order to produce industry output data in constant prices in a manner consistent with measures for the rest of the economy. This is a more promising approach to improving constant price industry and expenditure measures within the SNA framework than attempting such improvements through the collection of a vast array of quantity data. Construction industries sell specified configurations of materials-in-place which are, to borrow the jargon of other fields, sub-assemblies of some total system. As in other areas of industrial pricing, some of these products are simple and some are complex. Trade contractors sell these sub-assemblies or commodities mainly to an owner-builder or to a general contractor who, in turn, resells the trade contractors’ commodities along with whatever sub-assemblies the general contractor has produced. These sub-assemblies, when combined with, for example, the relevant outputs (or sub-assemblies) of manufacturers, the design services of service industries and the purchasers’ own contributions, yield the wide variety of plant and structures which constitute the various classes of gross fixed capital formation, which are not typically solely the outputs of the construction industries. The resulting contractors’ selling price indexes will provide deflators for the whole range of outputs of the various construction industries. These will become part of the system of industry selling price indexes from which relevant indexes for the various goods and services can be selected and combined with appropriate weights to yield arrays of deflators for the highly complex capital expenditures of business, institutions and government. Ultimately this integrated system of construction industry statistics will permit the preparation of gross output and value added measures, in both current and constant prices, to be calculated for the construction industries as an integral part of the Canadian System of National Accounts, as well as provide a key element for improving the deflation of fixed capital formation.     

What can we learn from a large border effect in developing countries?

Failure of the law of one price (LOP) in the short run is an empirical regularity. Recent research, using disaggregated price data for different cities across an international boundary, has shown that the variation of the prices in equidistant cities located in two different countries is systematically larger than that for the cities within the same country. Nontariff barriers and exchange rate variability are cited as the proximate causes of this systematic difference in consumer price variability. Results using data from developing countries with large nontariff barriers and more volatile exchange rate suggest that those claims are overemphasized.     

FDI与房价

本文在存量模型基础上,构建了一个外资参与的房地产市场局部均衡模型,考察了外资对房价的影响。理论模型显示,需求环节外资流入将导致房价上涨,开发环节外资流入将导致房价下降。本文使用中国35个大中城市1996-2010年的房地产市场和FDI数据,发现开发环节外资（FDI）对中国大中城市房价具有显著负向影响。另一方面,FDI与房价的影响是非对称的,FDI对房价的影响大于房价对FDI的影响。因此,为抑制高房价,在对需求环节外资（“热钱”）严格限制下,应鼓励外资进入房地产开发。此外,收入是影响房价的最主要因素;城市化越快,房价越容易上涨。     

MONOPOLY POWER AND DOWNWARD PRICE RIGIDITY UNDER COSTLY PRICE ADJUSTMENT

A method of 'backward deduction' is used to analyse the decisions of a firm, setting price and quantity before demand observations are made, with the option to adjust price at a cost after demand is observed. It is shown for such a firm that the events of (1) downward price rigidity; (2) overproduction; and (3) a high degree of monopoly power are closely related. The paper distinguishes itself from the previous literature on costly price adjustment in its treatment of disequilibrium situations and focus on monopoly power in relation to price rigidity. The main results are obtained for a linear demand curve and a uniform demand distribution.     

分税制改革、财政分权和房价水平

1998年房改以来,中国城镇房价持续快速上涨,引起了社会公众的广泛关注。本文发现,较高的房价水平总是与较高的财政分权度联系在一起的,而较高的财政分权度又与1994年的分税制改革密切相关。本文采用2000-2008年的分省面板数据,研究分税制改革背景下财政分权度对房价的影响机制,为上述假说提供实证证据。结果表明,分税制背景下逐年扩大的财政分权度是导致房价持续过快上涨的不可忽视的制度性因素。在使用了不同的计量方法、识别技术以及控制了其他潜在影响房价的因素后,本文的估计结果依然是稳健的。     

OWN‐ AND CROSS‐PRICE ELASTICITIES FOR GAMES WITHIN A STATE LOTTERY PORTFOLIO

Lotto demand modeling typically focuses on a single game and evaluates whether estimated “effective price” (expected loss from buying one ticket) elasticity is consistent with net revenue maximization. However, a portfolio of several different lottery games is now usually offered to players and judging the effectiveness of agencies in generating revenue requires estimation of both cross‐price and own‐price elasticities. Here we employ data from Spain to derive elasticities. Results imply that games are under‐priced if net revenue maximization is the goal. But the cross‐price estimates suggest that the operator is successful in limiting the extent to which a large jackpot on one game cannibalizes same‐week sales of other games. The paper also analyzes the impacts from two increases in the level of entry fees introduced during the data period. These appear to have affected net revenue favorably.

房地产税、市场结构与房价

本文在住房流量模型的基础上,构建了一个购房者和开发商的住房市场局部均衡模型,考察了完全垄断和完全竞争情形下房地产税与房价之间的关系。结果表明,无论何种市场结构,提高房地产税均导致房价下降;住房市场垄断性越强,房价越高,房地产税对房价影响越大。笔者对1996-2008年中国33个大中城市数据的检验发现,市场结构对房价影响大于房地产税。房地产税增长率每增加1%,房价增长率将减少0.03%;勒纳指数每增加1%,房价增长率将增加0.16%。房地产税与市场结构相互作用将使房价上涨,但影响微不足道。因此,对住宅开征房地产税,将对房价上涨有一定限制作用,但不能有效抑制房价上涨,而增强住宅市场竞争性、降低开发商垄断具有显著效果。     

ESTIMATING SPATIAL CONSUMER PRICE INDICES THROUGH ENGEL CURVE ANALYSIS

In this paper we propose a method of estimating spatial multilateral price index numbers from cross‐section consumer expenditure data on different items using Engel curve analysis. The novelty of the procedure is that it overcomes the problem of data inadequacy, a problem that is shared by most of the developing countries. The procedure does not require item‐specific price/unit value data and price index numbers can be calculated from consumer expenditure data grouped by per capita income/total consumer expenditure class in a situation where unit level data are not available. To illustrate the method, we use published state‐specific data of the 50th round (1993–94) and 55th round (1999–2000) consumer expenditure surveys of India's National Sample Survey Organization (NSSO) and calculate the spatial consumer price index numbers for 15 major states of India, with All‐India taken as base, separately for the rural and the urban sector for each round.
