交易成本与农户销售渠道选择——基于浙江省仙居县杨梅种植户的调查

笔者基于浙江省仙居县杨梅种植户的实地调查数据,利用Tobit模型,实证分析了交易成本对农户杨梅销售渠道选择的影响。研究结果显示,市场价格波动幅度、买主对杨梅质量认证的关注程度和单次平均销售数量促使农户从零售渠道转向贩卖商和加工企业渠道;交易前农户是否了解市场价格和果园到主要成交地点的距离促使农户选择零售渠道;户主年龄及种植面积对农户销售渠道选择也存在一定程度的影响,但其他家庭特征的影响则不显著。     

Heterogeneity and fine wine prices: application of the quantile regression approach

ABSTRACT

This study addresses the price heterogeneity of the five first growths of Bordeaux. We apply the quantile regression (QR) approach with market segmentation based on wine bottle price quantiles. We compute the hedonic price of wine attributes for various price segments in the market. This approach is applied to a major dataset comprising approximately 50,000 transactions over the 2003–2017 period. The findings indicate that the relative hedonic prices of several wine attributes differ significantly among deciles. The implications of our results are manifold. Vintage and Parker grades have a strong impact on the variation in wine prices, and there is a hierarchy among the five first growths of Bordeaux. There is also a premium commanded by the reputation and experience of an auction house. Since the financial crisis of 2012–2013, investors have considered that the five first growths are overrated, save for the most expensive wines; for those most expensive ones, investors prefer scarcity to liquidity. These results are of import to several actors in the fine wine market: investors, for example, could use the findings herein to better diversify their wine portfolio, while auction houses could better anticipate their future sales based on consumers’ expectation.     

Key market values for bottled wine in an emerging market: product attributes or business strategy?

ABSTRACT

This article focuses on the emerging bottled Chilean red wine market and studies the main determinants of the consumer price of wine sold on the domestic market. A hedonic price function was estimated for a sample of 810 wines using a quantile regression (QR) model. The database contains three variable groups to explain price: objective variables (national, international and vine quality designations), subjective variables (wine score) and business strategies used by wine producers. Results show that some objective variables have a greater impact on price than the wine score (a subjective variable) and business strategies, which vary for each quartile of prices analysed. Finally, this information will allow companies to design and implement marketing strategies to inform the consumer about the importance of some variables in the price of their product.     

The Dynamics of Markups and Inventories in Retailing Firms

This paper is concerned with the interaction between price and inventory decisions in retailing firms and its implications for the dynamics of markups and the existence of sales promotions. We consider a model where a monopolistically competitive retailer decides price and inventories, and assumes lump-sum costs when placing orders or changing nominal prices. In this model, the existence of stockout probabilities and fixed ordering costs generate a cyclical price behaviour characterized by long periods without nominal price changes and short periods with very low prices ( i.e. sales promotions). We estimate this model using a unique longitudinal dataset with information about retail and wholesale prices, inventories, orders, and sales for several brands in a supermarket chain. Based on the estimated model we perform several counterfactual experiments that show the important role that inventories and fixed ordering costs play in the dynamics of retail prices and the frequency of sales promotions in this dataset.

The NOME law: implications for the French electricity market

In December 2010, France approved the law “Nouvelle Organisation du Marché de l’Electricité” (or NOME law) to promote competition in the retail electricity market. In practice, the law allows retailers to buy nuclear production from the incumbent, at a regulated access price. This mechanism works up to a ceiling of 100 terawatt hours, which represents one quarter of the incumbent’s production from nuclear plants. Each retailer is assigned a share of that amount proportionally to its portfolio of clients. We contribute to the debate raised by the NOME law regarding the evolution of retail market prices. We show that a price decrease results if the ceiling is sufficiently high compared to the market share of the retailers competing with the incumbent. This pro-competitive effect is stronger when the incumbent’s rivals take into account the impact of their market strategy on the redistribution rule. Finally, we find that, if the regulated price of the NOME electricity is set above the nuclear cost, the incumbent realizes a gain that may result in strategic withholding, weakening the pro-competitive effects of the law.     

Federal excise tax increase and its effects on U.S. tobacco production

Using the equilibrium displacement model, we examine the impact on tobacco farms of the decrease in cigarette sales due to the increase in prices induced by the federal excise tax hike that went to effect on April 1, 2009. First we estimate the effect of the increase in the federal excise tax on cigarette price and sales. Then, we estimate the effect of the decrease in cigarette sales on tobacco farms. Results suggest that under a scenario of market power implied by a conjectural elasticity of 0.11 manufactures could charge $0.23 per pack more than the federal excise tax increase, which would be enough to offset the estimated 1.42 billion-pack sales decline and to maintain the industry’s revenue net of taxes. This decrease in cigarette sales induced by the increase in the federal excise tax would result in the tobacco leaf output and price declining by 2.85 and 0.41%, respectively. As a result, the tobacco leaf sector would sustain a loss of 3.25% in revenue, amounting to nearly $48.4 million.     

The Canadian border and the US dollar: The impact of exchange rate changes on US retailers

This paper provides a micro‐level investigation into the impact of changes in the US–Canada nominal exchange rate on retailers in US regions lying close to the US–Canada border. Using a large data set on product‐level retail prices and sales in the United States over a nine year period, we explore the links between changes in exchange rates, cross‐border travel and the price and quantity responses of US retailers. This allows us to assess the importance of geography and distance in affecting the pass‐through of exchange rate changes into prices and quantities at the level of the consumer. We develop a two‐stage theoretical model of cross‐border travel and industry equilibrium for retail sales at the border. Our empirical results accord well with the implications of the model.     

Price transmission and local market power: empirical evidence from the Austrian gasoline market

We analyse the impact of local market power on price margins and different dimensions of price adjustment dynamics (speed and asymmetry of price transmission) using data for a large number of individual gasoline stations in Austria. Specific attention is paid to threshold effects in price adjustment. Our results clearly suggest that the speed of price transmission between the Brent crude oil index and retail diesel prices is higher in a more competitive environment. While evidence on the relationship between local market power and asymmetries in the speed of price adjustment is mixed, our findings regarding asymmetries in price thresholds are clear: in regions where competition from neighbouring rivals is weak and/or consumers’ price elasticity of demand is low (stations located on the highway), positive thresholds significantly exceed negative ones, which corresponds to the ‘rockets and feathers phenomenon’. As expected, we observe that prices are lower in more competitive local markets.     

Does asymmetry in price transmission exist in the rice market in Sri Lanka?

This study analyses asymmetry in price transmission between wholesale and retail rice markets in Sri Lanka, using the threshold autoregressive model. We found that the wholesale and the retail rice markets in Sri Lanka are integrated, with price changes moving from the wholesale to the retail market. However, the price transmission process is asymmetric. In particular, price increases at the wholesale market transmit immediately to the retail market while price decreases transmit more slowly. Parameter stability test and follow-up analysis indicated that the price transmission process is asymmetric only during periods of price surges, suggesting that the rice market is not efficient during these periods.     

Pre‐sale information and hammer prices for Australian Indigenous art

Using sales data from 1987–2011 we investigate the role that pre‐sale price information plays in determining hammer prices for Australian Indigenous artworks. Importantly, we control for the degree of market concentration as this might influence buyers’ perceptions of fairness in relation to price estimates which are provided by auction houses. Auction houses therefore act as important intermediaries between art sellers and art buyers. The results suggest that pre‐sale estimates and market concentration have a differential impact on hammer prices, depending on the point in the conditional realised price distribution under examination.     

ILLEGAL MUSIC DOWNLOADING AND ITS IMPACT ON LEGITIMATE SALES: AUSTRALIAN EMPIRICAL EVIDENCE

This paper explores illegal music file‐sharing activity and its effect on Australian sales of singles in the physical and digital retail markets. Using fifteen weeks of Australian Recording Industry Association weekly chart rankings of physical and digital sales, combined with a proxy for download activity derived from the popular peer‐to‐peer (P2P) network Limewire, the evidence suggests no discernible impact of download activity on legitimate sales. Whilst significant negative correlation between chart rank and download activity is observed in the digital market, once download endogeneity is purged from the model and song heterogeneity is controlled for no significant relationship remains.     

Fire sales by euro area banks and funds: What is their asset price impact?

The assets under management of investment funds have soared in recent years, triggering a debate on their possible implications for financial stability. We contribute to this debate assessing the asset price impact of fire sales in a novel partial equilibrium model of euro area funds and banks calibrated over the period between 2008 and 2017. An initial shock to yields causes funds to sell assets to address investor redemptions, while both banks and funds sell assets to keep their leverage constant. These fire sales generate second-round price effects. We find that the potential losses due to the price impact of fire sales have decreased over time for the system. The contribution of funds to this impact is lower than that of banks. However, funds’ relative contribution has risen due to their increased assets under management and banks’ lower leverage and rebalancing towards loans. Should this trend continue, funds will become an increasingly important source of systemic risk.     

Determinants of price elasticities for private labels and national brands of cheese

An Almost Ideal Demand System model is developed and used to estimate price elasticities for US cheese sold at retail. Growing consumption of cheese coupled with fierce competition between private labels and national brands serves as motivating factors for this study. Per capita consumption of cheese grew by 75% during 1980–2004 and private labels captured a rising share of this growth. Private labels today account for 35% of market share; national brands, for the remaining 65%. Kraft accounts for 45% of national brands, but price increases for Kraft brands led to a sizeable price gap between its brands and private labels. This gap helped to stimulate growth of private labels. Marketing managers seek to capitalize on both growing cheese sales and price gaps for brands. Relevant information for marketing managers is consumer sensitivity to price changes. This study uses 69 weeks of scanner data, with consumers segmented by income levels to derive price elasticities for both lower-and higher-income consumers. Results show lower-income consumers to be more price sensitive. If large price gaps are maintained, the results suggest continued growth of private labels. Yet, meta-analyses for this study suggest that Kraft could lower the price gap and regain market share.     

A tale of two Italian cities: brand-level milk demand and price competition

We apply the BLP random coefficient logit model demand model to fluid milk sales data from two north-south Italian cities: Turin and Naples. By virtue of their location and socioeconomic differences, these cities provide a natural experiment for contrasting consumer choices and retail market power related to milk physical and marketing characteristics. Results reveal that, regardless of location, consumers negatively value price increases, fat content and ultra-high temperature (UHT) treatment. However, location matters with respect to brand and type of milk purchased. While in Turin (the higher-income region) demand for the leading manufacturers’ brands is the most price inelastic, in Naples consumers have the lowest price elasticities in case of cheaper milk, often small manufacturer or private label brands. Unlike previous studies, we do not find price elasticities for private labels to be consistently lower (or markups to be higher) compared to manufacturer brands, indicating that private labels have reached maturity in these markets. Further, while demand for fresh milk is more price inelastic in Turin, it is more inelastic for UHT milk in Naples. Likewise, markups and Lerner indexes are higher for fresh milk in Turin and for UHT in Naples corresponding to the more inelastic demands under Bertrand price competition.     

网上销售的影响因素:利基与热门市场的对比研究

长尾理论表明,互联网更利于利基市场的发展。然而,近期有研究认为热门市场在网上更有优势。为了验证在线商家在这两类市场的不同表现,我们对淘宝网上的791家店铺的64万余种产品的销售数据进行了分析。结果表明,网上销售受到信誉、产品多样性、价格、口碑以及被推荐机会等因素的影响,并且这些影响在利基和热门市场上表现出显著的差异。其中,信誉、产品多样性、价格和口碑对利基产品销售的影响更大。基于历史数据的被推荐机会对热门产品的销售有正向影响,而对利基产品的销售有负向影响。此外,我们还发现了网上销售的后发优势。     

On the Effects of Suggested Prices in Gasoline Markets

There is a widespread suspicion that suggested prices act as a focal point for individual firms when setting their prices. Oil companies announce suggested prices for gasoline stations in the Dutch retail market. We show that, compared to the gasoline spot market price, suggested prices contain additional information that explains retail price changes. We conclude that suggested prices have a horizontal coordinating effect in the sense that retail prices react to information that suggested prices contain and that is unrelated to firms’ costs (i.e., the information that firms use under normal competitive conditions).     

Effects of packers’ inventory and market power on price adjustments in the U.S. beef industry

This study examines effects of packers’ inventory and market power on their price adjustment behaviour in the U.S. beef industry. Econometric model used in the study allows inventory and market power variables to influence the speed-of-adjustment parameters in a three-regime threshold error-correction model. Results show that the two variables have a statistically significant impact on packers’ price adjustment behaviour when price decreases but not when price increases. When price decreases, inventory tends to accelerate the adjustment process whereas packers’ market power slows down the adjustment process. The hypothesis of symmetric adjustment towards long-run equilibrium during increasing and decreasing phases of price is not rejected when the effects of inventory and market power are considered in explaining packers’ price adjustment behaviour. However, when these two effects are ignored in the model specification, the hypothesis of symmetry is rejected such that the speed of adjustment in the increasing phase of price is faster than the adjustment speed in the decreasing phase of price, i.e. ‘rockets and feathers’ effect.     

The effect of the National Food Reserve Agency on maize market prices in Tanzania

Tanzania's National Food Reserve Agency has a mandate to ensure food security through procuring, reserving and recycling grain (primarily maize) in a cost‐effective manner. This mandate excludes a price stabilization role. Procurement prices, based on production costs, are often set above market prices to encourage production. Several disbursements channels exist: grain provided free or at a discount to targeted vulnerable households; subsidized sales to millers; and sales to prisons or nongovernmental aid programs, typically at market‐related prices. Given the perception that these activities are distortive, we use time‐series econometrics to model maize price dynamics in select wholesale markets to capture the Agency's market impact. We find that its pricing strategy had an insignificant impact on prices during 2010/11–2014/15 despite a fairly significant presence in at least some regional markets. We recommend that the Agency reconsiders offering a price premium on procured maize or selling maize at discount to millers, as limited market spill‐over effects imply the benefits are captured by only a few, even though its practice of providing subsidized or free maize to vulnerable people is not in question. Furthermore, current storage capacity expansion plans are not required and inconsistent with its food security mandate.     

我国粮食价格变动的经济效应分析

粮食价格变动的经济效应体现为对粮食产量、农民收入、物价的影响。从粮食市场价格形成的机制看,成本与资源禀赋决定粮价的长期走势,中期以市场自发调节为基础,政府干预为主导。本文通过对粮价与粮食产量、粮价与农民收入、粮价与物价之间的协整性和格兰杰因果关系检验,得出结论:粮食价格上涨能显著地刺激粮食增产、短期内激励农民增收,统计意义上粮食市场价格上涨不会引起物价上升,政府要继续利用粮食价格手段支持粮食增产与农民增收。今年粮食等主要农产品价格上涨不是引起通胀的主要原因,不能轻率地抑制农产品价格。
