How connected are Chinese farmers to retail markets? New evidence of price transmission

This paper examines the extent to which Chinese farmers are connected to regional agricultural markets by looking at the intensity of price transmission from retail markets to the farmgate. This intensity is indicative of the extent to which farmers might benefit from improved marketing opportunities and be exposed to price risks. We estimate the elasticity of farmgate prices to retail prices using price data for 170 markets, in 29 out of 33 provinces of China, at the detail of 12 main products and for the five-year period 1996 to 2000. In each province we find strong linkages between retail and farmgate prices with elasticities ranging between 0.6 and 1 and intensifying over time. This suggests that Chinese farmers are generally well connected to retail markets and that this connectivity has strengthened in the period considered, creating not only new opportunities but also new risks. It is also found that linkages are relatively weak in inland provinces, which is a point of concern in view of Chinese policies to create equal opportunities and equitable growth.     

What affects intranational price dispersion?: The case of Japanese gasoline prices

The empirical analysis on price dispersion, as described by [Engel, C., Rogers, J.H., 1996. How wide is the Border? American Economic Review 86, 1112–1125], is to investigate the determinants of international relative price fluctuations. Using data from the Japanese gasoline industry, we investigate the implications of the market structure for intranational price dispersion. Our empirical results suggest that: (1) in conformity with the double marginalization model, the dispersion of the wholesale gasoline price is affected by the relative retailer’s margin and (2) the dispersion of the retail gasoline margin is influenced by the degree of competition and advertising. Considering these results synthetically, the retail price dispersion is amplified by the retail market structure both directly and indirectly.     

The impact of world oil price shocks on macroeconomic variables in Vietnam: the transmission through domestic oil price

This study examines the impact of world oil price shocks on macroeconomic variables in Vietnam with a focus on the transmission channel of domestic oil prices. The Structural Vector Autoregression model with two blocks of real economy variables and monetary variables is employed. The world oil price follows an autoregressive process to reflect the exogenous nature of world oil price shocks to the domestic economy. The retail domestic oil price is determined simultaneously by only the world oil price due to the government's control of the domestic oil market. Using monthly data in the period between 2009 and 2021, the study indicates that a positive shock to world oil prices will increase the domestic oil prices significantly, industrial production (slightly and only statistically significant in the third month after), and inflation (significantly in 8 months). Besides, the domestic oil price is not the only transmission channel of world oil price shocks to the economy. This result implies forecasting, assessing, and controlling the impact of the world oil price shock on the economy should focus on both domestic oil prices and other indirect channels.     

Retail price concentration, transaction costs, and price flexibility circa 1900

This paper studies a unique 1901 data set containing prices of three products obtained from grocery stores in over 1400 cities nationwide. A striking characteristic is a high concentration of retail prices at relatively few “even” numbers. I propose a novel transactions cost explanation for this phenomenon on which existing theory is silent. In particular, grocers selected prices that simplified the task of toting up customer bills by hand and reduced related costs. As stores independently adopted this strategy across the country, prices converged to a few even numbers. Several empirical regularities for all three products are consistent with this explanation. An important implication is that preferences for computationally convenient prices would have made prices “sticky.” An independent study of price flexibility circa 1890 supports this hypothesis. The underlying data show price concentration patterns similar to the 1901 data, suggesting that the phenomenon covered a wide range of products.     

Energy price shocks,monetary policy and China's economic fluctuations

This paper develops a New Keynesian dynamic stochastic general equilibrium model with energy factors to study various channels through which China's economic fluctuations are linked to energy price shocks and to search for the optimal monetary policy to cope with energy price shocks. We conclude that there are channels through which changes in energy prices will have the following cause–effect relationships. First, a rise in energy price as a negative technology shock will raise the costs of providing capital services per unit of capital, thereby reducing output. Second, a rising energy price distorts the intertemporal choices of households and firms, creating downward pressure on the expected future return on capital. Third, an energy price shock places upward pressure on the marginal costs associated with an increase in inflation. Numerical simulation results show that a positive energy price shock has a positive effect on energy technology improvements. In addition, the effects of energy price shocks can be mitigated by nominal rigidities, and interest rate rules will determine the magnitude of those effects. Using the efficient frontier method, we also show that optimal monetary policy in China should help control energy price volatility.     

Markets under price controls in partial and general equilibrium

When parallel markets arise in the face of price or other controls, two aspects of agents' behavior become crucial in analyzing market outcomes. First, sellers' risk will rise with increases in illegal sales, but may also fall with increases in legal sales. If the latter is true, the parallel market price will induce higher output. Second, if consumers can be given access to the price-controlled good without incurring search, queuing and other transaction costs due to rationing, production of the controlled good will be higher. These effects are demonstrated in both partial and general equilibrium.     

Pricing on the Internet

It is often claimed that e-commerce has created a more competitiveenvironment by encouraging the entry of new online firms andby enabling buyers to search easily for the lowest prices. Thelimited evidence that exists paints a mixed picture. Many onlinemarkets are advertising- and technology-intensive, creatinga tendency towards growing concentration. Price search is imperfectand firms can dampen price competition by increasing productheterogeneity and switching costs. In many sectors, online firmsmay come to acquire some market power. We look at the formsof pricing that are likely to emerge in such markets, includingthe greater use of price discrimination and auction-like tradingarrangements.     

Optimal Monopolist Export Pricing with Dynamic Demand and Learning Curve Effects

This paper addresses incomplete exchange rate pass-through (ERPT) and pricing-to-market (PTM) by proposing an optimal control model of dynamic monopolistic pricing on a foreign market, which accounts for dynamic demand effects (such as diffusion or saturation) and learning curve effects. It is shown how the optimal dynamic export pricing results in partial or full ERPT in the long-term equilibrium. Moreover, transitional price dynamics are illustrated, which may explain dumping, i.e., temporary prices below unit costs, and (asymmetric) short-run overshooting dynamics of the optimal export price level as a reaction to exchange rate changes.     

The role of direct flights in trade costs

Effects of direct flights on trade costs are investigated using micro price data at the city level. After controlling for local retail/distribution costs, traded input prices are obtained to be further used in the measurement of trade costs across cities through arbitrage conditions. The existence of a direct flight enters trade costs regressions negatively and significantly. The results are shown to be robust to the consideration of many control variables, nonlinearities in the effects of distance on trade costs, possible endogeneity of having direct flights between cities and alternative definitions of the data. The direct flights that are shown to be determined by bilateral air services agreements are further shown to reduce trade costs through an endogeneity analysis; the main policy implications are twofold: (i) international trade policies through aviation services, such as Open Skies Agreements of the US, are alternative trade policy tools to reduce international trade barriers; (ii) direct flights facilitate the integration of internal markets as in the case of European Union.

Oil price shocks and Japanese macroeconomic developments

Using quarterly data for Japan over the period 1976:I–2008:II within a modelling strategy incorporating information about structural breaks in the variables included to represent the macroeconomic transmission channels, this paper shows that oil price shocks led to a fall in industrial production and higher inflation. However, these effects are only evident in the late 1970s and early 1980s. In more recent episodes of sharp oil price increases, inflationary effects are barely visible, and there is very limited evidence of oil‐induced industrial slowdowns.

The aggregate supply of output and a constant price level

Summary When they are treating the case of an economy operating at less than full employment macro theorists commonly assume that the aggregate supply function for output is perfectly elastic with respect to the price level. In this paper we demonstrate that an aggregate supply of output which is perfectly elastic at some price level cannot be derived from the interaction of the demand for and supply of labor in a competitive market even when the labor supply conditions are Keynesian in nature - e.g., rigid money wage rates.     

Regional Mc parity: do common pricing points reduce deviations from the law of one price?

This paper analyses price differences of McDonald’s products in four different countries. I show that pricing at pricing points in different currencies may contribute to explaining deviations from the law of one price. Observing strictly equal prices is more probable if prices are set at psychological and fractional pricing points in a common currency. The latter is also found to reduce the size of price deviations. Additionally, price differences increase as transaction costs increase. Based on this data set there is no evidence that the euro has reduced price deviations.     

House price,fertility rates and reproductive intentions

This paper uses national representative data collected through population census and household surveys to estimate the effect of house price on women's childbearing behaviors and intentions. It shows that higher house price significantly lowers women's reproductive probability and that women aged 30 and under, who have been married for 3–5 years, and those with no children are more sensitive to such effect. A significantly negative fertility response to house price is observed among renter families and those with self-built houses, but the response is insignificant for home-owning families. Subsample analysis by child gender reveals that house price mainly affects the probability of male births. Furthermore, women in regions with higher house prices are more willing to have daughters whereas those owning more houses tend to have sons.     

品牌价格竞争的非对称效应

1989年,Blattberg和Wisniewski提出并证实了品牌价格竞争的非对称效应的存在,即在同等水平的促销情况下,高端品牌(HighTier)在市场份额上的获益要大于低端(LowTier)品牌,或者说低端品牌促销对高端品牌的影响要小于高端品牌促销对低端品牌的影响。这一理论对品牌选择研究和企业定价实践产生了深远影响。本文介绍了对这一理论的两种经济学和一种行为学解释,并对有关的实证研究进行了总结。     

Methodology and application of price analysis

Summary This paper deals with the relationship between the development of unit costs and prices of production factors and the development of the prices of final products. The investigation of these relationships during the various stages of production in the economic process, an activity called price analysis, may contribute to the analysis of inflation. In this respect the influence of the wage rate on the development of the prices of final expenditure is more considerable than the influence of the prices of imports of goods and services. However, taking into account the modifications in the structure of production, particularly regarding labour productivity and import substitution, the main explanation of the price increase in 1976 compared with 1970 of three categories of final expenditure,viz. exports of goods and services, private consumption expenditure and gross fixed capital formation of enterprises is to be found in the unit costs of imports of goods and services rather than in the unit labour costs. An earlier version of this paper was presented at the 17th General Conference of the International Association for Research in Income and Wealth, Gouvieux, France, August 17–22, 1981. The author thanks C.B.S. staff members for many fruitful discussions and he is grateful to a referee for his helpful comments.     

Price‐Match Announcements in a Consumer Search Duopoly

Using a model of sequential search, we show that announcements to price‐match raise prices by altering consumer search behavior. First, price‐matching diminishes firms’ incentives to lower prices to attract consumers who have no search costs. Second, for consumers with positive search costs, price‐matching lowers the marginal benefit of search, inducing them to accept higher prices. Finally, price‐matching can lead to asymmetric equilibria where one firm runs fewer sales and both firms tend to offer smaller discounts than in a symmetric equilibrium. Price increases grow in the proportion of consumers who invoke price‐matching guarantees and in the level of equilibrium asymmetry.     

Price Dispersion in Online Grocery Stores: An Analysis of the UK Market

Search costs is the key determinant of price variance in offline markets. Yet, despite the lack of significant search costs, it is observed that price dispersion in online grocery markets still exist. This paper explores the possible determinants of this phenomena through an empirical model. Price data was gathered for the period of thirteen weeks for twenty-one product categories. In essence, the findings suggest that there is an indication of a price-quality relationship, but more significantly, retailers undertake randomized pricing strategies, culminating in sporadic price changes across the given time period.     

Factor price equalization? The cointegration approach revisited

Conclusions Absolute factor price equalization across countries is a key prediction of the Heckscher-Ohlin-Samuleson model of international trade, one of the more influential “workhorse” models in economics. Despite its theoretical might, the factor price equalization hypothesis has received surprisingly little empirical support. In an important exception to the rule, Burgman and Geppert (1993) argue that this might be due to the neglect of the non-stationarity of the time series under consideration. And indeed, applying a cointegration approach to (nominal) unit labor costs in six major industrialized countries (Canada, France, Germany, Japan, the United Kingdom, and the United States), they find evidence of long-run factor price co-movement. This finding can be interpreted as being in line with equalization of factor prices amongst these countries.
