Gains From Price Rigidity

This paper shows that there are substantial gains from price rigidity in an imperfectly competitive economy. Firms can increase their profits by agreeing some markets as markets of long-term contracts, of which prices are determined in advance to other spot market prices. Although they determine prices non-cooperatively in both markets, the mutual commitment making some markets' prices predetermined induces a price–price spiral between firms, which results in substantial gains for both firms. These gains outweigh the cost of inflexibility arising from price rigidity even though demand fluctuation is large and marginal cost is increasing.

Vertical Product Differentiation When Quality is Scarce: The Case of n > 2 Firms

This paper describes a model of vertical product differentiation in which more than two firms compete in quality and price. Quality is of fixed supply, so firms participate in an auction to attain it. Firms then simultaneously choose prices. The paper determines equilibrium bids in the quality auction and the Bertrand equilibrium prices. In equilibrium one firm attains all the units of quality, but pays a price such that it, like the minimum-quality firms, earns zero profits. Aggregate welfare is computed, and is shown to decrease as competition increases.     

Exchange rate pass-through in deflation: The case of Taiwan

This paper incorporates deflation in an analysis of the relationship between the exchange rate pass-through and inflation. Using a nonlinear model based on monthly data of Taiwan's import prices from 1981 to 2008, we find that the degree of exchange rate pass-through is increasing in deflation. The increase becomes smaller when the price of oil is excluded. Evidence for pass-through increasing in deflation has not previously been found in the existing literature and presents a new understanding of the pricing behavior of firms. Poor profits in deflation cause firms to pass through most of the cost of exchange rate changes to their products to avoid exiting the market.

Relative importance of sticky prices and sticky information in price setting

The relative importance of price and information stickiness in price setting to model and explain inflation dynamics is investigated in this study. A structural model of inflation is developed and used which combines two different models of price setting behavior: the sticky price model of the New Keynesian literature and the sticky information model of Mankiw and Reis. In a framework similar to the Calvo model, I assume that there are two types of firms. One type of firm chooses its prices optimally through forward-looking behavior—as assumed in the sticky price model. It uses all available information when deciding on prices. The other type of firm sets its prices under the constraint that the information it uses is “sticky”—as assumed in the sticky information model. It collects and processes the information necessary to choose its optimal prices with a delay. This leads to the sticky price–sticky information (SP/SI) Phillips curve that nests the standard sticky price and sticky information models. Estimations of this structural model show that both sticky price and sticky information models are statistically and quantitatively important for price setting. However, the sticky price firms make up the majority of the firms in the economy. The results are robust to alternative sub-samples and estimation methods.     

Inflation pressure and price intervention: an ominous combination∗

Of the debate regarding the new round of surging inflation in China, structural opinion interprets inflation as a problem of structural price growth, mainly brought about by a price hike for selected commodities as a result of exogenous shocks from different sectors. In line with the explanation, various measures aiming to control prices have been implemented recently. On the basis of basic economic principles and empirical evidence drawn from four cases, this essay argues that price intervention policies are counter-productive in bringing inflation down.     

Impact of asset price fluctuation on China’s monetary policy: An empirical analysis based on quarterly data, 1994–2006

The strenuous fluctuation in global asset price in recent years has had a profound impact on the economic and social development of every country. An empirical analysis indicates that asset prices (the stock price index and real estate prices) are important endogenous variables affecting the interest rate reaction function of central bank monetary policy. With expected inflation as a given, each one percentage point rise in output gap will cause a 0.79 percentage point reduction in interest rates by the central bank and each one percentage point rise in real estate price will result in a 2.2 percentage point rise in interest rates. The stock price index does have an influence on the trends in monetary policy, but it is less salient than the impact of housing prices. We also show that monetary policy that employs asset price as an endogenous variable increases the central bank’s control in seeking to attain its objectives. Therefore we suggest that the central bank should make asset price fluctuation an endogenous variable and incorporate it into its forward-looking interest rate rule, in order to facilitate the healthy development of China’s markets for real estate, stocks and derivatives, energy and bulk commodities and maintain rapid, smooth, sustainable and harmonious economic development.     

Peak-load pricing in duopoly

In this paper, we consider peak-load pricing by duopolists that maximize profit (not social welfare). We compare price levels and profits across peak-load versus uniform pricing regimes. Our main result is that the introduction of peak-load pricing can plausibly reduce prices by making price competition more severe and thereby reducing profits. This result suggests that competing firms may engage in collusion by not committing to peak-load pricing. Therefore, from the regulator's perspective, it will be desirable to encourage firms to engage in peak-load pricing to intensify competition.     

Sticky prices and moderate inflation

Recent evidence shows that there is great heterogeneity in the price setting frequency across sectors, and that those changing prices frequently do so even under low inflation. What happens to price setting strategies of sticky price goods under moderate inflation? We built a dataset of monthly newspaper and magazine prices for Colombia, for the period 1960–2005, an exceptional example of prolonged moderate inflation. Within this macroeconomic scenario, and the novel database, we study the frequency of price adjustment, the relative importance of time- and state-dependent theories, and their evolution as inflation declined from moderate rates to single digits.     

3F冲击对中国通货膨胀的影响研究

本文选取全球通货膨胀率、国际能源价格、国际食品价格作为3F外部冲击的三个影响因素,应用扩展的菲利普斯曲线实证分析1981年至2011年的外部冲击因素与我国通胀率的长期关系,然后使用VAR模型对这些外部因素所产生的冲击效果做进一步探究。实证结果表明：短期内,全球通货膨胀率是导致国内价格水平上升的主要原因;随着时间的推移,国际能源价格与国际食品价格对于国内价格水平的影响力逐渐增强,且在中长期成为较为重要的影响因素。而通胀预期与产出缺口则是中长期影响物价的最主要因素。因此,为了抵御外部冲击对我国通货膨胀的影响,管理我国对于本国及全球通胀的预期、构建相应的价格缓冲机制、实施农产品进口渠道多元化战略等均是较为有效的手段。与此同时,也要防止经济过快增长,抑制由于投资需求带来的通货膨胀。     

Alcohol consumption in the UK, 1955–85: a system-wide analysis

As a consequence of economic reforms in China, firms have ben affected by three essential changes. First, instead of surrendering all profits to the Government, firms now pay tax on their profits according to a contract between them and the Government and retain the balance as their own controllable surplus. Second, the central economic plan determines only part of firms' production. After fulfilling the command plan, firms are allowed to adjust their production scale by the availability of inputs and the profitability of production. Third, most consumer and investment goods have two prices, a plan price and a market price. As most of the plan prices are always lower than the market prices, the latter play a basic role in determining firms' profits. After a decade of economic reforms, the important question is: can Chinese state enterprises perform like market entities? The analysis shows that Chinese firms in transition domimic the production behaviour of market-based, efficiency-oriented firms.     

The Yugoslav inflation: Some competing hypotheses

Various hypotheses about wage and price inflation in Yugoslavia are presented and tested empirically with quarterly data from the 1962–1972 period. Both theoretical literature and empirical evidence on the behavior of the self-managed firm are used to derive different models of wage determination. The wage-equation results indicate that labor-market conditions, inflationary expectations; and labor-productivity variables are significant determinants of the rate of growth of wages. The price equations, based on a modified cost-markup model consistent with the practices of Yugoslav firms, identify labor costs and aggregate demand as significant determinants of the rate of growth of prices.

ARE THERE ADVERSE INFLATION EFFECTS ASSOCIATED WITH NATURAL GAS DECONTROL?

The Natural Gas Policy Act (NGPA) will decontrol gas prices in 1985, and there is concern about its inflation and output effects. In this investigation of these concerns, two misapprehensions are remedied. First, inflation is primarily a monetary phenomenon so that a rise in energy prices affects the price level, but any impact on inflation is temporary. Second, while analyses of NGPA have assumed that the price of gas will achieve parity with petroleum, they have neglected decontrol's effect on OPEC's optimal price, Our estimates of the decontrol effect demonstrate that energy prices will fall, not rise     

The price normalization problem in imperfect competition and the objective of the firm

Summary. General equilibrium models of oligopolistic competition give rise to relative prices only without determining the price level. It is well known that the choice of a numéraire or, more generally, of a normalization rule converting relative prices into absolute prices entails drastic consequences for the resulting set of Nash equilibria when firms are assumed to maximize profits. This is due to the fact that changing the price normalization amounts to altering the objective functions of the firms. Clearly, the objective of a firm must not be based on price normalization rules void of any economic content. In this paper we propose a definition of the objective of a firm, called maximization of shareholders' real wealth, which takes shareholders' demand explicitly into account. This objective depends on relative prices only. Real wealth maxima are shown to exist under certain conditions. Moreover, we consider an oligopolistic market and prove the existence of a Nash equilibrium in which each firm maximizes the real wealth of its shareholders.

Inflation news and stock returns: market direction and flow-through ability

Previous studies of the short-run response of daily stock prices to announcements of macroeconomic news could be biased when responses in different scenarios cancel each other out. In our analysis of inflation news in the Spanish stock market, we consider market direction arguments and implement our study based on the sector of activity to control for the ‘flow-through’ ability of the firms in each industry. In general, our results are quite consistent with the ‘market direction’ and the ‘flow-through’ hypotheses. Unanticipated inflation news implies abnormal returns depending on the direction of the news, the state of the economy and the flow-through ability of the sector. The impact of positive surprises affects the abnormal returns of many more sectors than does the impact of negative surprises, especially in the low states of economy. These significant effects are mainly observed in industries that are characterised by low flow-through ability.     

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.     

Reconciling microeconomic and macroeconomic estimates of price stickiness

This paper attempts to reconcile the high estimates of price stickiness from macroeconomic estimates of a New-Keynesian Phillips curve (NKPC) with the lower values obtained from surveys of firms’ pricing behaviour. This microeconomic evidence also suggests that the frequency with which firms adjust their prices varies across sectors. Building on the insights of Carvalho (2006), we present Monte Carlo evidence that suggests that in the presence of this heterogeneity estimates of the NKPC obtained using conventional methods, such as GMM, are likely to considerably overstate the degree of aggregate price stickiness. Furthermore, if roundabout production is a characteristic of the economy the NKPC will falsely suggest that a sizeable fraction of prices are indexed to past inflation. These problems arise because of a type of misspecification and a lack of suitable instruments.     

Choosing between Time and State Dependence: Micro Evidence on Firms' Price‐Reviewing Strategies

Because of recent findings based on survey data, it is now well known that firms differ from each other with respect to their price‐reviewing strategies. While some firms review their prices at fixed intervals of time, others prefer to perform price revisions in response to changes in economic conditions. Some theories have been suggested to explain this. However, empirical evidence on the relative importance of the factors that determine the different strategies of firms is virtually non‐existent. In this paper, we help to fill this gap by investigating the factors that explain why firms follow time‐dependent, state‐dependent, or both time‐ and state‐dependent price‐reviewing rules. We find that the strategies of firms vary with firm characteristics that have a bearing on the importance of information costs, with the variability of the optimal price, and with the sensitivity of profits to non‐optimal prices.     

Market structure in congestible markets

This paper analyses market structure of industries that are subject to both positive and negative network effects. The size of a firm determines the quality of its product: when network effects are positive, a larger firm is of higher quality; when the effects are negative, a larger firm's product is of lower quality. Consumers have heterogeneous preferences towards quality (firm size), and firms compete in prices. Equilibria are characterised: for example, in any asymmetric equilibrium, it must be that congestion is not too severe. One consequence of this feature is that an increase in the number of firms in the industry can raise individual firms’ profits. Two factors can bound the number of firms in a free-entry equilibrium without fixed costs: expectations, and the ‘finiteness’ property (Shaked and Sutton, Review of Economic Studies 49 (1982) 3–13, Econometrica 51(5) (1983) 1469–1483) of price competition.
