Disentangling supply and demand shifts: the impacts on world salmon price

To understand price changes, one must determine the relative impact of supply and demand shifts on price. Conditional on predetermined supply and demand elasticities, we retrieve yearly shifts in regional supply and demand. The relative impact on price from each supply and demand shift is determined through an equilibrium displacement model (EDM). This procedure is applied on a yearly basis for the world salmon market in the period 2002 to 2011. The results indicate a large variation in demand and supply growth both over time and between regions. While average annual price impacts from supply or demand shifts from most regions are not statistically significant, price impacts from supply or demand shifts for specific periods are detected in all but one region. This indicates that the use of smooth trend indicators is likely to be inappropriate for measuring supply and demand shifts and their impacts on price. The procedure presented in this article can be a useful instrument for determining the relative impacts of supply and demand shifts on price in any market with unstable price behaviour.     

Price competition and the Bertrand model: the paradox of the German mobile discount market

We investigate the degree of price competition among telecommunication firms. Underlying a Bertrand model of price competition, we empirically model pricing behaviour in an oligopoly. We analyse panel data of individual pricing information of mobile phone contracts offered between 2011 and 2017. We provide empirical evidence that price differences as well as reputational effects serve as a signal to buyers and significantly affect market demand. Additionally, we find that brands lead to an increase in demand and thus are able to generate spillover effects even after price increase.     

Retirement and health behaviour

This article investigates whether and to what extent retirement changes health behaviour. For identification we use an instrumental variable approach that exploits exogenous variations in the early and normal retirement ages within and across 10 European countries. Our results reveal that among those who abstained from alcohol and vigorous or moderate exercise at baseline, retirement increased those activities. Non-smokers did not increase smoking upon retirement. Retirement led to less smoking for those who smoked before retiring. It also brought about an increase in vigorous exercise for those who had the behaviour at baseline. These results further vary by a person’s job type, but less so with respect to gender or geographic region. Overall, our findings provide new empirical evidence on the causal link between retirement and health behaviours and how such link relates to four sources of individual heterogeneity: gender, European geographic region, job type and baseline health behaviour.     

Dealer behaviour in the Euro money market during times of crisis

This article shows how the recent money market disruptions with elevated counterparty risks and uncertainty about the fundamental value of liquidity influenced the trading behaviour of a key dealer in the Euro money market. The complete trading record in the unsecured segment of the money market for 2007 and 2008 is used to estimate a stylized pricing model, which explicitly accounts for the over-the-counter structure. The empirical results suggest that the market maker learns from order flow, but this information aggregation was increasingly hampered as the crisis unfolded.     

On measuring speculative and hedging activities in futures markets from volume and open interest data

This article provides a critical assessment of the line of research that measures speculative and hedging activities in futures markets from volume and open interest data. It makes several contributions. First, a detailed theoretical analysis of the measures proposed in the previous literature as proxies for speculative activity clarifies the circumstances in which they fail, as well as the assumptions that have to be made, when they are used as intended. Second, we propose a new way of combining the volume and the open interest figures, which provides additional information regarding the type of trading activity that takes place in the market on a given date. Finally, we analyse empirically the basic statistical properties of all the ratios when they are applied to real data for some of the stock index futures contracts most actively traded in the world. This empirical analysis shows the diverse behaviour of the ratios when they are applied to a common sample of real data, which confirms our previous theoretical findings. Our contributions should be taken into account when any of the measures is used as a proxy for the relative importance of speculative demand in empirical analyses.     

Football spectator no-show behaviour in the German Bundesliga

Despite an extensive literature on stadium attendance demand, our understanding of those factors shaping spectator no-show behaviour is rudimentary at best. Here, we explore such behaviour by using a comprehensive two-step approach: First, we examine the determinants of no-show behaviour in the German Bundesliga between the four seasons 2014–15 and 2017–18; Second, because our initial results imply that spectator no-show behaviour is more prominent among season ticket holders (STHs), we exploit additional survey data to understand individual STH no-show appearances better. Our results suggest that club managers interested in reducing the no-show rate should rethink existing season ticket strategies.     

Herding behaviour and the declining value relevance of accounting information: evidence from an emerging stock market

This article sheds light on the underlying mechanisms behind the changes in the value relevance of accounting information in the Karachi Stock Exchange (KSE) during the 1999–2010 period. We find that neither changes in earnings quality nor the earnings lack of timeliness hypothesis can explain the decline in the value relevance of accounting information in the KSE. Based on the stylized facts associated with the growth of the KSE and the broader economics literature, we argue that the reduction in the explanatory power of accounting information vis-à-vis stock returns was caused by herding behaviour. Empirical estimates from state-space model of herding behaviour confirm the existence of herding, and we find that the value relevance of accounting information is significantly lower in periods characterized by herding behaviour. This article is also amongst the first attempts to empirically demonstrate that an expansionary monetary policy and increases in foreign portfolio investment lead to increased levels of herding.     

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.

The Demand for Food Products: An Analysis of Interpurchase Times and Purchased Quantities

In this paper we study household purchase behaviour of storable food products. An inventory model is developed in which the household chooses an optimal stock level of the product. Storage of the product is costly, there is a fixed cost per purchase occasion, and the market price is sometimes discounted because of price promotions. We show that the optimal purchase policy is an s , S policy. The model is used to derive predictions on the correlations between interpurchase times and purchased quantities on the one hand, and prices on the other. These predictions are empirically verified using consumer panel data.     

Asymmetric labour force participation decisions

This article finds compelling evidence of asymmetric labour force participation decisions across demographic groups in response to changes in labour market conditions. This behaviour is consistent with predictions from the standard labour-leisure choice model and suggests that asymmetry in individual behaviour plays some role in the observed asymmetry of the aggregate unemployment rate. It is estimated that the weighted average difference in response to a one percentage point change in unemployment rates is sizeable when compared to the average monthly change in the aggregate labour force.     

An analysis of consumption behaviour of foreign tourists in Ireland

The objective of this article is to analyse the consumption behaviour of foreign tourists in Ireland. Based on the Almost Ideal Demand System, five demand systems are estimated, four representing the major source markets of tourists to Ireland, namely from Britain, North America, Mainland Europe and Rest of the World; and one aggregate model based on a pooled sample. Each system included six commodity aggregates representing the major consumables of tourists. Estimated models were statistically significant and the derived elasticities are theoretically consistent and empirically plausible. While there are some variations in the consumption patterns of tourists from different source markets, reflecting differences in consumer preferences and consumption habits, in general, tourist demand for the various Irish tourism goods and services is found to be price inelastic. This finding is consistent with a priori expectations, as tourists are obliged to consume whatever is available at the destination they visit. The lack of substitutes and perfect information on product markets offer limited consumption opportunities for the tourists. Nonetheless, the cross-price elasticity values for all commodities across the source markets indicate gross complementarity, which suggests that latent price sensitivity exists in the background. This is an area that needs further investigation and this finding may have significant, yet unknown, consequences for repeat visitation.     

Further Evidence from Survey Data on Australian Manufacturing Price Changes*

Three data sets from two different quarterly surveys have been used in estimating six standard models of price change behaviour. Results for Total Manufacturing Industry, for all three data sets, show prices respond to both actual cost movements and commodity market excess demand conditions. For most ASIC two-digit industries, prices respond rapidly to actual cost movements, and for many industries they also respond directly to excess demand conditions. No single excess demand measure is appropriate for all industries. The magnitude of orders and inventories influences is very small, but capacity utilization contributions seem far from trivial. Industry results are frequently sensitive to the survey used and/or to the method used to weight individual firm's responses.

Re-examining the Chinese A-share herding behaviour with a Fama-French augmented seven-factor model

ABSTRACT

In view of the contradicting results in existing research, this article proposes a new weighted cross-sectional variance (WCSV) model to re-examine the level of herding behaviour in the Chinese A-share market. Motivated by the original WCSV model, we utilize a Fama-French augmented seven-factor model as the underlying Arbitrage Pricing Theory model, which introduces the trading volume and turnover rate factors to the Fama-French five-factor model. The regression results show the superiority of our new model compared to the WCSV model based on Fama-French three- and five-factor models, which implies that the empirical findings of herding with our WCSV model are more reliable in relative terms. In the empirical aspect, in addition to testing the herding level yearly and integrally, to provide further insight on the relationship between market stress and herding, we apply our model to the Chinese A-share herding behaviour within each of three well-known crisis periods. In addition, we also split the sub-samples into pre-crisis and post-crisis periods to detect the existence of asymmetric herding behaviour for different market directions. Our findings suggest that Chinese A-share herding behaviour is more prevalent during large market turmoil, especially under condition of down market.     

Toward a Wider Analysis of Market Definition: Theory and Evidence from the Turkish Telecommunications Industry

This article develops a novel approach to the analysis of market definition. The article empirically investigates the main components of market definition, such as market power, substitution, and the simultaneous interaction between the demand and its determinants for the fixed and mobile voice services. To this end, I employ the multivariate Johansen cointegration methodology and analyze the Turkish voice telecommunications industry. While the VECM analysis confirms the presence of a simultaneous long-term causality relationship among the variables, the Johansen normalization results reveal demand elasticities that enable the analysis of market power and fixed-to-mobile substitution. My findings suggest that the fixed and mobile voice services, which are traditionally viewed as separate markets, can be defined as products that compete in the single market.     

Employers' recruitment behaviour and vacancy duration: an empirical analysis for the Dutch labour market

The functioning of labour markets from a demand-side perspective is examined. In particular, the determinants of vacancy duration are studied in the context of a model of employers' search behaviour. A model for the choice of the recruitment strategy at the start of the search process and the corresponding recruitment duration is developed in which allowance is made for different patterns of duration dependence for each recruitment strategy. This model is applied to data on employers' search behaviour in the Dutch labour market. It is found that employers prefer advertisements as the first recruitment channel when applicants are required to have work experience. Moreover, employers prefer to start searching via the labour exchange office when jobs in the secondary segment of the labour market have to be filled. It is also found that - when advertisements are used as the first recruitment strategy - employers need some time to acquire a pool of applicants and to select candidates from this pool. It is interesting as a contrast that applicants seem to be evaluated rather quickly if employers start searching via informal contacts.     

Determinants of bank risk behaviour in EMU countries

This article investigates the determinants of banking sector risk behaviour in EMU countries over the period 2004Q4–2013Q3. Average ‘Distance-to-default (DtD)’ based on all publicly listed banks headquartered in a particular country is used as an indicator of banking risk. Macroeconomic fundamentals, market sentiments and gross debt-to-GDP together with private debt are considered as factors explaining risk behaviour. Using a panel framework, I found that the market sentiments, debt-to-GDP ratio and nonfinancial institutions debt significantly affect banking sector fragility.     

The impact of employers' recruitment behaviour on the allocation of vacant jobs to unemployed job seekers

This paper is focused on the allocation of vacant jobs to job seekers from a demand side perspective by studying the recruitment behaviour of employers. A model is developed to analyze the role of search and selection methods of employers as determinants of the probability that an unemployed person will be hired for a certain type of job. In an empirical application for the Dutch labour market, we have examined the effect of employer's recruitment behaviour on the allocation of vacant jobs to employed, unemployed and school-leaving job seekers.We find that job requirements for the applicants with respect to work experience are the most important determinant of the probability that an unemployed person will be selected to fill a vacant job. In addition, the use of advertisements by employers for jobs requiring high skill levels does also have a significant effect.     

Welfare analysis in a two-stage inverse demand model: an application to harvest changes in the Chesapeake Bay

Like many agricultural commodities, fish and shellfish are highly perishable and producers cannot easily adjust supply in the short run to respond to changes in demand. In these cases it is more appropriate to conduct welfare analysis using inverse demand models that take quantities as given and allow prices to adjust to clear the market. One challenge faced by economists conducting demand analysis is how to limit the number of commodities in the analysis while accounting for the relevant substitutability and complementarity among goods. A common approach in direct demand modeling is to assume weak separability of the utility function and apply a multi-stage budgeting approach. This approach has not, however, been applied to an inverse demand system or the associated welfare analysis. This paper develops a two-stage inverse demand model and derives the total quantity flexibilities which describe how market clearing prices respond to supply changes in other commodity groups. The model provides the means to estimate consumer welfare impacts of an increase in finfish and shellfish harvest from the Chesapeake Bay while recognizing that harvests from other regions are potential substitutes. Comparing the two-stage results with single-stage analysis of the same data shows that ignoring differentiation of harvests from different regions, or the availability of substitutes not affected by a supply shock, can bias welfare estimates.     

Shatterbelts and conflict behaviour: The effect of globalisation on ‘high risk’ states

This article ties together seemingly disparate literatures (those of globalisation and ‘shatterbelt states') as a means of investigating the changing conflict behaviour of high‐risk states. The objective of this research is to ascertain empirically whether the circumstances that generate aggression by high‐risk states are the same as those for others. In addition, by examining how conflict behaviour has changed over time, and in conjunction with trade openness, these tests speak to the importance of economic interdependence as a mitigating counterforce to aggressive tendencies. The results indicate that domestic instability and fragmentation are more directly tied to high‐risk state behaviour than are systemic influences. In contrast, the probability that low‐risk states originate or participate in conflicts, and resort to violence, is tied to international factors. Surprisingly, increased repression seems to result from the opposite circumstances. For high‐risk states, changes in repressive behaviour are tied to the external environment while low‐risk states seem prone to change levels of repression in conjunction with their internal conditions. Lastly, and most importantly, trade openness has an important pacifying effect on high‐risk states, but appears to be irrelevant to the conflict behaviour of all others. Globalisation, it appears, mitigates the violence that is often initiated by high‐risk states. These results offer important preliminary evidence for understanding high risk‐states and the strategies that may reduce their aggressiveness.
