DYNAMICS BETWEEN NORTH AMERICAN AND EUROPEAN AGRICULTURAL FUTURES PRICES DURING TURMOIL AND FINANCIALIZATION

North American and European agricultural futures markets faced significant changes in recent years, i.e., the financialization which originated in the USA, the increase of futures trading in Europe and the recent price turmoils in international commodity markets. We analyse the long‐ and short‐run dynamics between North American and European agricultural futures prices during these institutional changes. The empirical results show that the US markets lead in terms of price transmissions and volatility spillovers. US markets, however, predominantly react to deviations from the long‐run equilibrium which indicates a rising impact of European agricultural markets on a global scale.     

Price competition in the market for business telecommunications services

We estimate a two-step control-function model that relates incumbent prices for small-business telecommunications services to the number of facilities-based entrants, cost, demand, regulatory conditions, and a correction for endogenous market structure. Results show that the price effects from entry are understated in ordinary least squares regressions. When controlling for endogeneity, prices are negatively related to the number of entrants, indicating that markets without a competitive presence could exhibit market power. These findings should prove helpful to the Federal Communications Commission and other State regulators determining the conditions under which price and other forms of regulation may be relaxed.     

Dynamic demand and noncompetitive pricing strategies

This paper studies optimal noncompetitive pricing strategies when the evolution of demand is the result of intertemporal considerations. Two different hypotheses of price expectations (myopia and perfect foresight) are treated. The major implication is that the slight modification from an instantaneous to a very fast consumer reaction may completely modify a monopolist's price strategy. More precisely, the price strategy should be volatile if the equilibrium demand is convex, independent whether the consumers act myopically or employ rational expectations. On the other hand, asynchronous dynamics (e.g., due to competitive fringe supply or different segments of demand) cannot explain even damped price oscillations. The equilibrium price strategy of the noncompetitive supplier exceeds the static rule if consumers employ myopic expectations; rational expectations may lead to prices above or below the static rule depending on the rate of discount.I am grateful for the helpful and elaborate comments from three anonymous referees.     

House price dynamics: Evidence from Beijing

To study the house price dynamics in China, this paper extends the traditional life-cycle model by incorporating land supply, regime shifts and government regulation factors. The models are estimated with an error correction framework using quarterly data from 2000 to 2007 in Beijing. The conclusions are as follows. (1) There exits a stable co-integration relationship between house price and fundamentals; land supply and financial regimes are also important determinants of long-run equilibrium house prices. (2) Short-run dynamics depend on changes of fundamentals and the adjustment process of housing market. Land supply has a significant impact on house price fluctuations while demand factors such as user costs, income and residential mortgage loan have greater influences. The adjustment speed of real house prices to the long-run equilibrium has been reduced significantly since 2005 which means exogenous shocks can cause prolonged deviation of real house prices from the equilibrium level.     

Cross market predictions for commodity prices

This paper shows that commodity prices can be predicted from cross-market information by establishing long-run cross-market commodity price equilibrium models, which are characterized by a linear relation between prices across different markets. Using data from five representative commodity markets (oil, copper, gold, corn, and cattle) during the period 2005–2018, we demonstrate that oil and industrial metal markets have formed a long-run price equilibrium with other markets across different commodity families. However, agriculture and gold markets do not tend to have long-run price equilibrium relations with other commodity markets. Furthermore, we show that the absence of a price equilibrium is due to the cross-market liquidity interference effect. After we control for the liquidity effect, long-run cross-market commodity price equilibrium relations are reestablished for agriculture and gold markets. These results can aid in demonstrating that liquidity can capture most of the missing information that is not reflected in price dynamics in less liquid markets, such as agriculture and gold markets. Therefore, less liquid commodity price predictions require both prices and liquidity levels from cross-markets, while liquid commodity prices (oil and metal) can be predicted based solely on cross-market prices.     

Rationing rule, imperfect information and equilibrium

Summary. The impact of imperfect information on the price setting behaviour of firms is analysed. Specifically, consumers support an information cost to become informed about prices. Firms are endowed with U-shaped average cost curves. If a firm does not supply more than its competitive supply as determined by its marginal cost schedule, then we show that the existence of a pure strategy equilibrium is conditional on the rationing rule employed. If uninformed consumers are served first then the monopoly price is the sole equilibrium whenever consumers' information costs are high enough. Otherwise, a pure strategy equilibrium fails to exist contrary to the results of Salop and Stiglitz (1977) or Braverman (1980) who implicitly suppose that firms supply all the demand at a given price.

Study on the price co-movement among the Asia Pacific,European and Chinese coal markets – based on the empirical analysis of MS-VEC model

In this article, based on weekly data of the three major coal markets (the Asia Pacific, Europe and China) from March 2008 to November 2014, an empirical research on their mutual influence and price co-movement effect among the three major coal markets is conducted by using the Co-integration Theory, Granger Causality Test and markov switching-Vector Error Correction (MS-VEC) model. The conclusions are as follows. (1) There exists a long-term cointegration relationship and bidirectional causality relationship between coal prices at home and abroad, and the influences of foreign coal markets on the domestic coal markets are stronger than the influences of domestic coal markets on foreign coal markets, and thus the interaction between the two markets leads to asymmetric linkage effects. (2) Compared with the VEC model, the MS-VEC model can reflect the nonlinear feature of price co-movement effects. (3) There exists an inherent adjustment mechanism between domestic and foreign coal markets, i.e. the coal prices will be self-revised continuously until a long-term equilibrium state is achieved when a deviation from the equilibrium state occurs. (4) There exists a co-movement effect which varies with the change of regime among the three coal prices, and the self-maintenance is strong and the status transfer phenomenon is clear in different regimes.     

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.     

Search cost,trading strategies and optimal market structure

The theory of Walrasian equilibrium yields a set of prices at which the aggregate competitive demand for each commodity equals its aggregate competitive supply. However, even at equilibrium prices the theory of competitive equilibrium does not explicitly offer explanation regarding the manner in which trades are actually executed. This paper considers a model where trade takes place in a decentralized fashion and examines in a dynamic game-theoretic framework, the role of social institution of money and markets in facilitating exchange. The steady state Nash equilibrium derived in the paper demonstrates how, depending on the level of transaction costs associated with a market setup (synonymously, trading posts to exchange possible pairs of goods) appropriate monetary trade emerges, which like a hub and spoke network (Starr and Stinchcombe, 1999) makes some markets non-functioning and in equilibrium only the markets having trade through the medium of exchange continue to exist. However, despite the obvious advantages of a market setup in reducing search costs, pure random search for a complementary trading partner (as considered by Ostroy and Starr, 1974; Kiyotaki and Wright , 1989; and others) prevails in many economies, especially, in many developing economies. This paper models this feature of developing economies by introducing differences in transaction costs across agents and shows why sustainable equilibria might exist exhibiting random search for certain commodities even in the presence of established markets.     

A history of European electricity day-ahead prices

In this article, we examine the development of day-ahead prices in five European markets which became more connected over recent years. Where previous studies examined the convergence of price levels over time, we focus on patterns in estimates for the parameters in a switching regimes model. This makes it possible to distinguish between prices under normal market conditions and under non-normal market conditions, those market conditions that can cause extreme price spikes. We expect that increased connectivity yields additional supply in the short-term and therefore will reduce the impact of price spikes. Our results indicate that the impact of price spikes and volatility decreased over time, that prices behave more random, and that the parameter estimates between various connected markets seem to have converged between the Belgian, Dutch, French, German and Nordic day-ahead markets over the years 2003 through 2010. These results can be explained by increased connectivity and improved liquidity.     

Microeconomic modeling of parallel markets: The case of agricultural goods in the USSR

In a centrally planned economy, non-market-clearing prices fixed by the state cannot be used directly to estimate consumer behavior models. This paper represents an attempt to overcome this problem by utilizing prices in a parallel “free” market. An equilibrium model incorporating parallel markets is discussed and a demand curve arising from this model is estimated using data for the markets for meat and milk in the USSR. the price and income elasticities of demand for these goods are found to be significantly higher than those estimated for the United States.     

连续进化金融模型与全局渐进化稳定策略

本文运用达尔文生物进化论思想研究连续交易金融市场选择的动态变化及一般均衡规律。本文发现并证明了:金融资产“赢利”的充要条件是该资产相对股息大于相对股价;投资比例等于股息分发比例的简单混合策略是全局渐近进化稳定策略;在均衡条件下,对应的金融资产价格等于该资产股息占总股息的比例的数学期望;市场变异或金融创新是有效市场形成的动力;全局渐近进化稳定策略业绩可能在某些时候不是最好的,但只要其初始财富大于零,最终将控制市场上的所有财富,而简单混合策略,可能在某个时候业绩优良,然而,在市场存在全局渐近进化稳定策略的条件下,只要其初始财富份额小于1,最终控制的财富趋向于零,从而被市场所淘汰。     

Will euro area house prices sharply decrease?

The long-term euro area house price equilibrium and its short-term dynamics are estimated by means of a panel error correction model. The estimates show that the short-term dynamics are essentially driven by the autoregressive term (persistence), disposable income and mortgage loans, whereas interest rates have little effect. The long-term house price equilibrium is mainly driven on the demand side by disposable income, interest rates, and mortgage loans, whereas costs (mostly land) drive the equilibrium on the supply side. The unprecedented long-lasting boom in house prices from 1997 to 2007 is thus essentially explained by a favourable macroeconomic development caused by the EMU effect and a glut of global savings. The bust phase of euro area house prices began in 2007, and the current house price might return to its equilibrium level in 2014. According to the most realistic scenario, euro area house prices will experience a smooth and soft landing in 2016 and then begin an increasing phase that will be pulled upwards by a higher equilibrium price. However, a deflationary scenario cannot be excluded if the current credit squeeze is not solved, particularly in the peripheral euro area member states.     

The supply of non‐renewable resources

There exists no formal treatment of non‐renewable resource (NRR) supply, systematically deriving quantity as function of price. We establish instantaneous restricted (fixed reserves) and unrestricted NRR supply functions. The supply of a NRR at any date and location depends not only on the local contemporary price of the resource but also on prices at all other dates and locations. Besides the usual law of supply, which characterizes the own‐price effect, cross‐price effects have their own law. They can be decomposed into a substitution effect and a stock compensation effect. We show that the substitution effect always dominates: a price increase at some point in space and time causes NRR supply to decrease at all other points. Our new—although orthodox—setting takes into account not only NRR supply limitations but also the heterogeneity of NRR deposits, and the endogeneity of their development and opening. Our analysis extends to NRRs the partial‐equilibrium analysis of demand and supply policies. Thereby, it provides a generalization of results about policy‐induced changes on NRR markets.     

A dynamic simulation model of the world jute economy

This paper investigates both the sources of jute supply instability and the potential impact of an internationally managed buffer stock to stabilize market prices. The analysis is carried out utilizing a rather simple dynamic model of the markets for raw jute and jute goods. The model combines econometric estimates of the relevant parameters with a priori information derived from industry studies. It integrates the behavior of jute farmers in the principal jute growing countries with that of jute goods manufacturers and consumers using a series of region-specific demand and supply functions. Expected price variance is an explicit factor in determining jute acreage.     

Equilibrium Effects of Superstition in the Housing Market

We investigate the interaction of product quality differentiation and consumer preference heterogeneity in durable goods markets, focusing on the effects of secondary market liquidity and consumer heterogeneity on equilibrium prices. We build an infinite‐horizon dynamic model of the apartments housing market that captures the above features. Some apartments are considered lucky, and some consumers are superstitious. Lucky apartments are valued more highly than non‐lucky ones only by superstitious consumers. Results show that the difference between the lucky apartment price and the non‐lucky apartment price becomes smaller when the secondary market becomes less liquid and when consumers’ preference heterogeneity becomes more persistent as opposed to time‐varying.
