Incomplete Credit Markets and Commodity Marketing Behaviour

We use a simple theoretical model of seasonal market participation in the presence of liquidity constraints and transaction costs to explain the ‘sell low, buy high’ puzzle in which some households do not take advantage of inter‐temporal price arbitrage through storage and sell output postharvest at prices lower than observed prices for purchases in the subsequent lean season. We test our model with data from western Kenya using maximum likelihood estimation of a multivariate sample selection model of market participation. Access to off‐farm income and credit indeed seem to influence crop sales and purchase behaviours in a manner consistent with the hypothesised patterns.     

Measuring the cost of liquidity in agricultural futures markets: Conventional and Bayesian approaches

Estimating the cost of liquidity in agricultural futures markets is challenging because bid‐ask spreads are usually not observed. Based on an ability to reflect simulated data from Roll's spread model, we assess the effectiveness of conventional and Bayesian bid‐ask spread estimators under different market conditions. Conventional serial covariance and absolute price change spread estimators appear to be biased. Hasbrouck's Bayesian estimator generates small costs of liquidity whose values depend on the correlation and noise in the data. The absolute value Bayesian estimator is precise and works well under conditions of high levels of noise and correlation usually found in agricultural futures markets. Using data from live cattle (LC) and lean hog (LH) contracts, we find similar patterns of performance that produce economically meaningful cost of liquidity differences.     

Keynes and a post-Keynesian controversy over the effect of debt on income expansion

The paper considers arguments of Robertson (1938) and Asimakopulos (1983) that the Keynesian multiplier expansion of output may be constrained by debt implicitly incurred in the financing of autonomous investment necessary to start the multiplier process. The task of this essay is to show that within the ‘short-period’ and static analytical framework of Keynes, this line of reasoning regarding the adverse effects of debt on multiplier-induced expansions of output is unwarranted. Nevertheless it is concluded that if the Keynesian framework is abandoned in favour of a dynamic framework in the manner of a steady trend rate of growth - a choice dependent on how one conceives of the economy, as inherently static or dynamic - then such arguments have troubling implications. In particular, the dependence of Keynes's approach on credit and hence debt forges links between ‘short-periods' whose distinctness from one another is crucial to Keynes's result.

Liquidity and market makers: a pseudo-experimental analysis with ultrahigh frequency data

An analysis is given of the effect of market makers on liquidity using a transaction-level database. For this purpose, the focus is on a financial market where a change in regulations created explicitly the category of market maker in 1997 and that date is used to construct a pseudo-experiment. In contrast with other studies that use ultrahigh frequency data, the days to be analysed are selected using a statistical procedure to match observations before and after the change in regulation. The propensity score is used to perform the matching. After choosing the days, an estimate of an ordered probit model is made to explain the intraday behaviour of price changes. The coefficient estimates from the ordered probit model are used to calculate a measure of liquidity based on the steepness of the response function of price changes to volume. The results show that liquidity, measured in this way, has not been affected by the introduction of the market makers.     

Excess Liquidity,Housing Price Booms and Policy Challenges in China

Incorporating asymmetric cost and benefit of supplying excess liquidity into an otherwise standard time inconsistency model, this paper offers an explanation of the excess liquidity and housing price booms recently experienced in China. We find that the central bank's incentive to stimulate economic growth with excess liquidity fuels real estate prices and accelerates inflation bias. Therefore, the central bank should free itself from the pressure to achieve an economic growth rate higher than the potential level, and assign an appropriate weight to the real estate price fluctuations in the central bank's objective function, so that the central bank's policy of stimulating economic growth with excess liquidity can be constrained.
