Stabilizing consumer choice: the role of ‘true dynamic stability’ and related concepts in the history of consumer choice theory

Abstract

It is often argued that the inability of Arrow–Debreu general equilibrium theory to produce an adequate proof of the stability of the Walrasian price adjustment mechanism was one of the program's most significant failures. This paper will not question this standard interpretation of the history of general equilibrium theory, but makes the case that characterizing the ‘stability’ question in terms of market stability– in particular the stability of the equilibrium price vector in the Walrasian general equilibrium model – actually helped to stabilize the standard model of consumer choice in general equilibrium theory and elsewhere within microeconomics. The problem of the stability of ‘consumer's equilibrium’ was much discussed early in the twentieth century, and it has recently re-emerged in a different guise as the ‘endowment effects’ and ‘reference dependencies’ of contemporary behavioral economics, and yet it disappeared from mainstream discussion during the period 1950 to 1980. This paper argues that shifting the discussion from the intra-agent stability of the individual consumer to the inter-agent stability of the competitive market contributed – despite its ultimately negative impact on general equilibrium theory – to the long period of stable normal science consumer choice theory enjoyed during the middle of the twentieth century.     

Network position and firm performance – the mediating role of innovation

Analysing a unique, domain-similar database including all horticulturalists in a major flower-producing country, this paper shows that a firm’s central position in a network significantly improves its financial performance. The effect of strategic positioning in a network is in large part mediated through its enhanced innovativeness. Strategically positioning in a network of firms contributes more to firm performance, both directly as well as indirectly, than other strategic options a firm has available, such as seeking scale, seeking to diversify, pursuing cost advantages, or locating in a cluster.     

Politics of scale and strategic selectivity in the liberalisation of public services – the role of trade in services

One of the most contentious issues of the neoliberal agenda has been the privatisation of public services. The WTO GATS negotiations over the liberalisation of trade in services, which commenced in the year 2000, led to a strongly contested debate over whether the international level would provide an additional channel for the privatisation of public services. In particular, the position of the European Union was criticised for promoting this agenda. More recently, this question has regained its significance with the start of negotiations for the Trade in Services Agreement and the Transatlantic Trade and Investment Partnership. Thus, this article seeks to analyse the politics of scale in the field of trade in services and its specific impact upon the liberalisation of public services. By applying a Neo-Poulantzian IPE approach, we propose a typology of (i) scalar forms in trade policy and (ii) of particular liberalisation strategies. Our results suggest that the multilateral level is but one element in a strategic politics of scale, with the former primarily fulfilling the role of locking-in liberalisation gains achieved at other levels, while other scalar forms, in particular bi- and plurilateralism, are primarily used to progressively advance the liberalisation agenda.     

Macroeconomic expectations and consumer sentiment during the COVID-19 pandemic: The role of others’ beliefs

This paper investigates the effect of information about cross-country ratings of the government’s and the public’s reaction to the COVID-19 pandemic on consumers’ macroeconomic expectations and sentiment. We conduct consumer surveys with randomized control trials (RCTs) in two waves in Thailand and Vietnam. The information treatments have the strongest effect when the information shown contradicts consumers’ prior beliefs. In the first survey, conducted when the first lockdown was eased, treatment effects are stronger in Vietnam, causing more optimistic expectations and sentiment. In the second survey, conducted at the start of the second wave of infections, treatment effects are stronger in Thailand, causing a more pessimistic outlook.     

The role of uncertainty in the euro crisis – an application of liquidity preference theory

The world financial crisis triggered a rediscovery of the active role fiscal policy can play as a remedy in such situations. During the euro crisis, escalating funding costs in a number of southern eurozone member states and Ireland have called this strategy into question. One interpretation of the euro crisis concentrated on the public debt trends in those countries. Opposing this view, the main point of this contribution is to elaborate the link between rising interest rates on sovereign bonds in the euro crisis and a major feature of the financial crisis – a subdued degree of investor confidence after the Lehman collapse. Theoretically, this link is developed with reference to Keynes’ liquidity preference theory. The high explanatory power of measures for the degree of confidence in financial markets as well as detrimental effects of fiscal austerity on the evolution of sovereign yield spreads are demonstrated empirically by means of panel regressions and supplementary correlation analyses.     

Absorbing radical ideas from unusual sources – the role of social integration mechanisms

If companies rely strongly on internal R&D and existing networks their ability to introduce radical innovations may suffer. Opening up to new idea sources may provide a solution. Incumbent companies, however, often suffer from the tendency to reject radical ideas from unusual sources. This study investigates how social integration mechanisms (SIMs; coordination, socialisation, and systems mechanisms) influence an incumbent steel company’s absorptive capacity (AC). A micro-level analysis of two radical ideas from unusual sources contributes to AC and radical innovation literatures by exploring relationships between SIMs and four AC capabilities (acquisition, assimilation, transformation, and exploitation). The findings suggest that AC capabilities are context-specific with respect to innovation novelty and idea source. The results emphasise the negative sides of socialisation and formalisation mechanisms, and the positive effects of coordination mechanisms on the AC capabilities in such high uncertainty contexts.     

Lending technologies,banking relationships,and firms’ access to credit in Italy: the role of firm size

This paper analyses the role of lending technologies and banking relationships on firms’ credit access in Italy. Using EFIGE firm-level data, we show that the depth and strength of firm–bank relationships have heterogeneous effects on credit demand and rationing probabilities depending on the size of the borrower. Multiple banking relationships alleviate financial constraints for small firms, while borrowing from a large number of lenders hinders access to credit for large companies. Small and medium-sized enterprises with a higher share of debt with the main bank have a lower probability of being credit denied, as debt concentration contributes to overcome the opacity problems typical of the SMEs. Long-lasting relationships, by reducing information asymmetries, significantly improve access to credit for small and large firms. Conversely, we find that medium-sized enterprises are more exposed to financing constraints as relationship duration increases, due to possible lock-in effects. Finally, firms maintaining banking relationships based on transactional technologies are more likely to be credit denied, while the use of relationship lending technologies improves credit availability for both small and large enterprises.     

The role of rare earth prices for consumer prices: an ignored factor?

The article explores the role of a new determinant that accounts for driving consumer prices, i.e. rare earth prices. Rare earths are used for many advanced manufacturing and military technologies. Performing a number of panel methodological approaches, panel cointegration findings support the initial insight of the authors and illustrate a positive effect on consumer prices across all rare earths.     

Is there an energy paradox in fuel economy? A note on the role of consumer heterogeneity and sorting bias

From the previous literature, it can be found that consumers tend to undervalue discounted future energy costs in their purchase decisions for energy-using durables. We show that this finding could, in part, result from ignoring consumer heterogeneity in empirical analyses as opposed to true undervaluation.     

How important is the credit channel in the transmission of monetary policy in Mexico?

This article empirically examines the importance of the credit channel of monetary policy in Mexico for the period 2004–2013. We estimate a vector autoregressive (VAR) model to analyse the effects of a monetary policy shock on real output, and we also use a threshold VAR model to investigate asymmetric effects of contractionary and expansionary policies. The empirical results suggest that a contractionary monetary policy results in a fall in the supply of loans together with an increase in the spread between the lending and deposit rate. To the extent that some borrowers are dependent on bank loans for credit, the reduced supply of loans amplifies the effects of monetary policy on output associated with the traditional interest rate channel. Our results also suggest that the importance of the credit channel is larger for contractionary shocks than for expansionary shocks.

A DEA study to evaluate the relative efficiency and investigate the reorganization of the credit department of farmers’ associations in Taiwan

In this study data envelopment analysis models were applied to evaluate the relative efficiencies of the credit departments of farmers’ associations (CDFAs) in Taiwan. The findings show that the overall efficiency scores are not best and scale for CDFAs in Taiwan is relative small. It implies that the reorganization of the CDFAs may be appropriate if more efficient organization is to be pursued. Thus, this study investigated CDFAs reorganization to increase the efficiency. The proposed CDFAs reorganization alternatives have higher average efficiency scores than the current CDFAs.     

Models of mortality rates – analysing the residuals

The area of mortality modelling has received significant attention over the last 25 years owing to the need to quantify and forecast improving mortality rates. This need is driven primarily by the concern of governments, insurance and actuarial professionals and individuals to be able to fund their old age. In particular, to quantify the costs of increasing longevity we need suitable model of mortality rates that capture the dynamics of the data and forecast them with sufficient accuracy to make them useful. In this article, we test several of the leading time series models by considering the fitting quality and in particular, testing the residuals of those models for normality properties. In a wide ranging study considering 30 countries we find that almost exclusively the residuals do not demonstrate normality. Further, in Hurst tests of the residuals we find evidence that structure remains that is not captured by the models.     

The role of the German Historical School in the development of Mises’s thought

Hülsmann (2007) and Hayek ([1922] 1981) have argued that Mises’s first book The Development of the Relationship between Lords of Manor and Peasants in Galicia, 1772–1848 (1902) is written in the tradition of the German Historical School. Historicist contemporaries of Mises also considered his first academic work a continuation of the Knapp-Grünberg tradition (Kaser Jahrbuch für Gesetzgebung, Verwaltung und Volkswirtschaft im Deutschen Reich, 28(1), 374–79, 1904; Wimbersky, 1906). We argue that von Mises (1902) does not represent the younger German Historical School. First, Mises provides a rationalization of the history rather than ethical and cultural explanation of historical events. Second, he does not support the Knapp-Grünberg argument about the historical development of serfdom under a Slavic rule. Finally, von Mises (1902) does not adhere to the ideology of the Historical School regarding the virtues of the Prussian bureaucracy.     

Financing difficulties for SMEs and credit rationing – an expanded model of mortgage loans with asymmetric information

This article presents a new model of mortgage loans under reasonable assumptions. A several key variables that affects the success of a project, such as project risk, total investment, lending rate,mortgage, and self-financing are jointly considered in the model. The model takes the participation constraints and the incentive compatibility constraints into account for enterprises and banks on project investment actions respectively. Our model can explain the coexistence scenario of small medium enterprises’ (SMEs) financing difficulties and credit rationing in credit markets with asymmetric information. It reveals that higher enterprise self-financing for the project is a “credible factor” to the bank. Banks put forward strict requirements on mortgage for the SMEs with low proportion of project self-financing, which will lead to two scenarios:one is that some SMEs would not get loans due to insufficient mortgage assets; other is that some SMEs will voluntarily give up loans because of loan requirements, even if they have enough mortgage assets. Rationing is implemented both to large enterprises and SMEs, but the degree of rationing is gradually strengthened with the reduction of self-financing scale for the project.     

China’s CO2 emissions from power generating stations and the role of subsidies – a first exploration

Our analysis is the first of its kind to explore patterns of subsidization and CO₂ emissions in China’s electricity-producing sector. Applying data for all power plants across China and controlling for the age, capacity and location of generating stations, we find that plants attracting a higher government subsidy are also the plants generating a disproportionate share of CO₂ emissions. This distortion is incongruent with China’s aspiration for a greener economy but may be eliminated if China delivers on its November 2013 announcement to review many industry subsidies on its way to a fully fledged market economy.     

Does the impact of private education on growth differ at different levels of credit market development?

Using an overlapping generations model, we show that the impact of private financing of education on growth depends on credit market development, being positive when credit markets are adequately developed but negative if sufficiently low levels of credit market development occur alongside relatively high private financing intensities. Employing cross-country data, we find that reduced-form growth relationships are statistically significant and robust under various controls and samples. We also lay out conditions under which economies with missing credit markets are dynamically efficient and outperform, in terms of growth, economies with complete credit markets. The latter may explain large cross-country differences in savings and growth, while facilitating the evaluation of policies on financing education.     

Improving the predictability of the oil–US stock nexus: The role of macroeconomic variables

In this study, we revisit the oil–stock nexus by accounting for the role of macroeconomic variables and testing their in-sample and out-of-sample predictive powers. We follow the approaches of Lewellen (2004) and Westerlund and Narayan (2015), which were formulated into a linear multi-predictive form by Makin et al. (2014) and Salisu et al. (2018) and a nonlinear multi-predictive model by Salisu and Isah (2018). Thereafter, we extend the multi-predictive model to account for structural breaks and asymmetries. Our analyses are conducted on aggregate and sectoral stock price indexes for the US stock market. Our proposed predictive model, which accounts for macroeconomic variables, outperforms the oil-based single-factor variant as well as the constant returns (historical average) model for both in-sample and out-of-sample forecasts. We find that it is important to account for structural breaks in our proposed predictive model, although asymmetries do not seem to improve predictability. In addition, we show that it is important to pre-test the predictors for persistence, endogeneity, and conditional heteroscedasticity, particularly when modeling with high-frequency series. Our results are robust to different forecast measures and forecast horizons and are useful for making effective hedging decisions in the US stock market.     

The behaviour of the US consumer price index 1913–2003: a study of seasonality in the monthly US CPI

This article analyses the seasonality in the monthly consumer price index (CPI) over the period January 1913 to December 2003. We examine three types of month effects: if the mean of monthly CPI changes of the entire data set, and of a given month were significantly different from zero; if the mean of monthly CPI changes of a given month was different from the mean of the other months; and if the variance of the monthly CPI changes for a given month was different from the variance of the other months. The mean of monthly CPI changes for the entire data set (0.27%) was found to be significantly greater than zero. The means of monthly changes show a downward trend from September to December. When the data are sliced into three sub-periods, we find an increasing trend in the means and medians of monthly changes but a decreasing trend in the SDs of the monthly changes. The mean of monthly CPI changes during the republican presidencies (0.15%) was significantly lower than during the democratic presidencies (0.38%).
