The cyclical behaviour of prices in the U.K.: Some structural time series evidence

The cyclical behaviour of prices in the U.K. is investigated using a sample of annual observations covering the period 1886–1993. A structural time series model relating consumer prices to output is estimated over four sub-periods. The results indicate that prices were procyclical in the inter-war period, countercyclical in the post-1973 period and acyclical otherwise. The proposition that the cyclical behaviour of prices is determined by the dominance of supply or demand shocks alone is disputed on the basis of empirical evidence and theoretical reasoning. It is concluded that the cyclical behaviour of prices cannot be explained just by analysing time series on output and prices and that due attention should be paid to the institutional and policy changes occurring during the period under study. It is demonstrated that the empirical results are consistent with the events experienced by the U.K. economy in the most recent period.

An empirical investigation of customer market analysis–a microfoundation for macroeconomics

The slow adjustment and stickiness of output prices is widely regarded as an important determinant of macroeconomic behaviour. Recently, a number of writers have argued that customer market analysis can provide a microfoundation for price stickiness. This paper develops the theory of a firm selling in a customer market and investigates the empirical implications of the theory. The model is shown to imply a particular pattern of behaviour between retail prices and wholesale prices. Data on retail and wholesale prices for the United States, the United Kingdom and Australia at various levels of aggregation is investigated and found to support the predictions of the customer market model. In the conclusion the macroeconomic implications of the empirical conslusions are drawn out.     

Housing market cycles in large urban areas

This paper examines the behaviour of house prices in large metropolitan areas. Using a sample of metropolises it is shown that real estate prices are largely nonlinear. It is found that dynamic asymmetries in the housing market cycle can well be modelled using a logistic smooth transition model (LSTAR). Further, it is found that the LSTAR specification has better forecasting properties with respect to other linear and nonlinear models.     

Generalized beta distributions for describing and analysing intraday stock market data: testing the U-shape pattern

There is an impressive body of empirical evidence which indicates the existence of an intraday U-shaped curve in stock prices. In an effort to shed additional light on the U-shaped curve a new procedure for U-shape testing is introduced. From careful analysis of intraday data it is observed that minimum or maximum stock prices can occur several times during the day. Here, attention is focused on the first time during the day that the maximum or minimum stock price occurred. Because of the importance of the first time during the day that the maximum or minimum stock price occurred, an attempt is made to model these two characteristics with probability distributions. The objective of this study is to use a generalized beta distribution to examine the intradaily behaviour of stocks, using closing stock prices for each one-minute interval, using data from Athens Stock Exchange (ASE). This generalized beta distribution has not been used before to model U-shaped behaviour. The results are consistent with the intraday U-shaped curves, i.e. the time to first maximum (or minimum) stock prices follows a U-shaped pattern. In addition, some potential applications of the generalized beta distribution are discussed and exemplified by analysing the relationship between herd behaviour and U-shaped.     

A 'pricing-to-market' model with unobserved variables: explaining New Zealand's import prices

A model of ‘pricing-to-market’ (PTM) behaviour in import prices is developed for a small open economy to allow for two measurement problems: (i) that neither the marginal production cost of imported goods nor their corresponding (foreign-currency) export price are observable by the econometrician; (ii) that PTM behaviour, if it exists, alters the relationship between foreign countries' export price indices for total exports and the true, unobservable price index. The analysis shows that variations in the measured markup on import prices depends on the degree to which domestic demand is synchronized with world demand, whether bilateral exchange rate movements are due to domestic or foreign factors, and on the degree to which PTM behaviour differs from such behaviour in other countries. Equations estimated for the price of New Zealand (NZ) imports from the US strongly supports the model, and finds that the degree of PTM by US exporters in response to price and exchange rate movements is substantially greater in NZ than the average for other countries. However, the degree of PTM in NZ in response to excess demand is similar to that of other countries.     

The effect of quantitative easing on stock prices: a structural time series approach

A structural time series model is estimated and tested to examine the effect of quantitative easing (QE) on US stock prices. The model is estimated by maximum likelihood in a Time-varying parametric (TVP) framework, using the S&P 500 index as the dependent variable and the Fed’s balance as an explanatory variable in addition to the unobserved components accounting for the behaviour of variables that do not appear explicitly in the equation. The results show that QE had a sizeable, but not exclusive, effect on stock prices and that stock prices were also affected by other missing variables and cyclical movements. Several explanations are presented for the rise of the US stock market in the post-QE period, particularly since the election of Donald Trump.     

Should monetary policy lean against the wind? Simulations based on a DSGE model with an occasionally binding credit constraint

In this research paper, we extend the model constructed by Gambacorta and Signoretti (2014) by introducing an occasionally binding credit constraint based on a penalty function approach in line with Brzoza-Brzezina, Kolasa, and Makarski (2015) to study the performance of the Taylor rule augmented with asset prices. First, we compare the properties of the baseline model and its modified version. Then, we use both models to study the performance of the basic and extended Taylor rule. The performance of Taylor rules is examined under the optimisation of a central bank's loss function and the welfare maximisation of economic agents. The analysis delivers the following results. The model with an occasionally binding credit constraint has more favourable properties regarding the hump-shaped and asymmetric impulse responses compared to an eternally binding credit constraint model. The best rule regarding the lowest value of the central banks' loss function proves to be the rule augmented with asset prices. The optimal reactions are, however, shock- and model-dependent, and therefore, any rule-like behaviour does not seem to be appropriate. The welfare maximisation under the occasionally binding credit constraint model reveals that reacting to asset prices might not be welfare-improving for both types of economic agents – households and entrepreneurs. This result is in contradiction with the implications achieved under the eternally binding credit constraint model.     

Rockets and feathers behaviour in the Spanish gasoline and diesel market: New evidence

In this paper we analyse the potential asymmetric response of retail prices for gasoline and diesel‐fuel to changes in oil prices for the Spanish economy and its relation with the so‐called ‘rockets and feathers’ behaviour. We show that the assumption made by previous studies, which use as the key explanatory variable the sign –positive or negative‐ of the change in international oil prices, is inadequate for the Spanish case and the magnitude of the change in international oil prices is also relevant. For small changes in international oil prices there is neither price asymmetry nor rockets and feathers behavior in the retail markets. However, price asymmetries in line with rockets and feathers behavior in retail gasoline and gasoil markets are present when these changes exceed a certain threshold. Following Martín‐Moreno et al. (2018) we first apply an Auto‐regressive Error Correction Model and endogenously estimate the threshold triggering the rockets and feathers behaviour. A time‐varying nature for the dynamic response of retail prices to oil price shocks is revealed when we estimate the TAR‐ECM model using rolling windows. Hence, in a second stage, we use a Markov‐switching estimation of the model to test the robustness of the results given its suitability to changing environments. This study could have relevant policy implications for the Spanish gasoline and gasoil retail markets due to the ongoing debate on the existence of a rockets and feathers behavior in gasoline and gasoil retail markets between the Spanish regulatory body and the oil companies.     

AN OPEN-ECONOMY NEW KEYNESIAN PHILLIPS CURVE: EVIDENCE FROM HONG KONG

Abstract. This paper extends the new hybrid Keynesian Phillips Curve (NKPC) to the open‐economy context. We hypothesize that pricing decisions depend on both labour costs and intermediate imported input prices. The results for Hong Kong are consistent with the theory if import prices are given substantial weight in measuring marginal cost, rejecting the labour costs model. We find that forward‐looking behaviour is dominant, and that price stickiness is smaller in Hong Kong than in the USA. The results are sensitive to the choice of instruments, and a model using the output gap instead of marginal cost as the forcing variable also performs well.     

The price of owning a car: an analysis of auction quota premium in Singapore

Faced with dilemmas parallel to countries besieged by road congestions and limited land resources, Singapore has chosen to adapt a Vehicle Quota System (VQS) whereby car owners are required to bid for a licence in an auction before their vehicles are allowed onto the road. In this study, the behaviour of VQS auction prices is examined using a structural time series approach. For outliers that are not observable from innovations, auxiliary residuals with dummy variables are used to supplement the analysis. In general, prices exhibit a fairly constant seasonal pattern. The inclusion of monthly VQS quotas released by the transport regulatory body and the national stock market index is not useful in explaining the observed price behaviour. Interestingly, a basic structural model with stochastic components seems to fit the data best.     

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.     

Optimal search behaviour in a model with increasing costs

A search model incorporating increasing search costs and limited duration of price offers is investigated. It is shown that optimal behaviour is characterized by increasing reserve prices.     

Inflation and growth in a disequilibrium macroeconomic model

The purpose of this paper is to study the dynamics of temporary equilibria in a disequilibrium growth model. Dynamics rests upon adjustment mechanisms of prices, capital stock, money balances, and labour supply. Wage dynamics is supposed to be influenced by indexation processes, and this question is related to the investment behaviour of firms. We give sufficient conditions for existence, unicity, and asymptotic stability of steady states of this model. We also show that steady states correspond to a long-run Phillips curve, which is vertical when inflationary expectations are fully reflected in wage and price changes.     

PORTFOLIO BEHAVIOUR AND ASSET PRICING IN A CHARACTERISTICS FRAMEWORK

We have applied the characteristics model to the problem of portfolio behaviour and asset pricing. By defining assets in terms of characteristics, we generated individual demands for assets which depended on the prices of assets, the technological relationship between assets and asset characteristics, and the individual's preferences for different characteristics. In general, the characteristics model cannot be readily aggregated across individuals. However, when we assumed that the assets-characteristics technology had a simple form which was common to all individuals, market-clearing conditions could be used to derive an asset pricing model. Finally, we showed that the characteristics model provides a unified approach to the problem of preference-based portfolio behaviour and asset pricing. A number of existing models can be interpreted as characteristics models: the state-preference model, the parameter-preference model, the capital asset pricing model and the inter-temporal capital asset pricing model.     

Market Organisation and Trading Relationships

In this paper we give a theoretical model of buyers' behaviour on a market for a perishable good where no prices are posted. We show that if buyers learn from their own previous experience there is a sharp division between those who learn to be loyal to certain sellers and those who continue to 'shop around'. This feature remains in more general models which are simulated and is consistent with empirical data from the Marseille fish market.     

Price setting in Indian industry

Price setting models with variable mark-up rates are specified and estimated for four sectors of Indian industry. It is found that capacity utilisation has a significant effect on mark-up rates implying a Phillips curve type trade-off between output and prices. International prices do not appear to be as important in the price-setting behaviour of firms.     

Asymmetric Adjustment Costs, Asymmetric Pricing and Employment: Evidence from the UK

This paper uses an asymmetric multivariate model to investigate asymmetries in employment and pricing behaviour by firms. This generalises the approach of Granger and Lee (1989) and also exploits the cross equation restrictions on the equations for prices and employment implied by a restricted cost function—the dual to a Cobb‐Douglas production function. Our results suggest that both prices and employment respond asymmetrically to shocks to costs and demand.     

Can oil prices help predict US stock market returns? Evidence using a dynamic model averaging (DMA) approach

Crude oil price behaviour has fluctuated wildly since 1973 which has a major impact on key macroeconomic variables. Although the relationship between stock market returns and oil price changes has been scrutinized excessively in the literature, the possibility of predicting future stock market returns using oil prices has attracted less attention. This paper investigates the ability of oil prices to predict S&P 500 price index returns with the use of other macroeconomic and financial variables. Including all the potential variables in a forecasting model may result in an over-fitted model. So instead, dynamic model averaging (DMA) and dynamic model selection (DMS) are applied to utilize their ability of allowing the best forecasting model to change over time while parameters are also allowed to change. The empirical evidence shows that applying the DMA/DMS approach leads to significant improvements in forecasting performance in comparison to other forecasting methodologies and the performance of these models are better when oil prices are included within predictors.     

Mispricing of Risk in Sovereign Bond Markets with Asymmetric Information

The likelihood that a government will repay its sovereign debt depends both on the amount of debt it issues and on the government's future ability to repay. Whilst the former is publicly observable, the government may have more information about the latter than investors. This paper shows that this asymmetric information problem impairs the market's ability to differentiate economies according to their fiscal sustainability, and can lead to a disconnect between bond prices and default risk. The model can help rationalise the behaviour of Eurozone bond prices prior to the recent European sovereign debt crisis.     

Trade liberalisation and exchange rate pass-through: the case of textiles and wearing apparels

Studies on the relationship between exchange rates and traded goods prices typically find evidence of incomplete pass-through, usually explained by pricing-to-market behaviour. Although economic theory predicts that incomplete pass-through may also be linked to the presence of non-tariff barriers to trade, variables reflecting such a link is rarely included in empirical models. In this paper, we estimate a pricing-to-market model for Norwegian import prices on textiles and wearing apparels, controlling for non-tariff barriers to trade and shift in imports from high- to low-cost countries. We apply the cointegrated VAR approach and develop measures of foreign prices based on superlative price indices (including the Törnqvist and Fischer price indices) and a data calibration method necessary to approximate relative price levels across countries. Our measures of foreign prices thereby account for inflationary differences and varying import shares and price level differences (known as the China effect) among trading partners. We show that these measures of foreign prices, unlike standard measures used in the pricing-to-market literature, are likely to produce unbiased estimates of pass-through. Once the China effect is controlled for, we find little evidence that pass-through has changed alongside trade liberalisation.
