Is There a Causal Effect of Working Part‐Time on Current and Future Wages?

In this paper, I study the causal effects of part‐time work on current and future wages. To estimate these effects, I use a random effects model with a wage equation capturing the employment history and a dynamic multinomial probit component for the choice of employment status. Exclusion restrictions from the institutional context are exploited to support identification. The results suggest that working part‐time with few hours has a large causal effect on current wages, but more extensive part‐time work does not reduce current wages. However, both types of part‐time work lead to negative long‐term wage effects.     

Can the Timing of Negotiations Impact the Consequences of Mergers?

This paper uses a theoretical model to examine whether variation in the timing of negotiations between buyers and sellers can alter the effects of mergers between sellers. The model shows that mergers between horizontally overlapping firms lead to price increases regardless of how negotiations take place. In contrast, mergers between firms in different markets can only lead to higher compensation for the combined firm when negotiations occur sequentially. However, any price effects from out‐of‐market mergers stem from a mechanical redistribution of existing market power and not from a loss in competition. Published 2014.

Financial functional analysis: a conceptual framework for understanding the changing financial system

The financial system is currently undergoing a revolution brought about by e-finance, digital convergence, new market entrants and government-encouraged competition. New market entrants such as Apple, Alibaba, Facebook and Google come from industries such as IT, retail, social media and telecoms, and, therefore, do not fit comfortably within traditional financial institutional structures. A functional perspective might provide more practical insights into this revolution; however, the functional perspective has had a limited impact. This paper will investigate the benefits and limitations of financial functional analysis; probe the underpinning principles of sociology’s structural functional analysis; revisit Merton and Bodie’s (1995) six core financial functions in relation to new entrants in the financial landscape; and, finally, argue that in the new financial environment, functional analysis provides a more coherent and explanatory framework of the financial system for students and practitioners alike.     

Two-stage DEA: <Emphasis Type="Italic">caveat emptor</Emphasis>

This paper examines the wide-spread practice where data envelopment analysis (DEA) efficiency estimates are regressed on some environmental variables in a second-stage analysis. In the literature, only two statistical models have been proposed in which second-stage regressions are well-defined and meaningful. In the model considered by Simar and Wilson (J Prod Anal 13:49–78, 2007), truncated regression provides consistent estimation in the second stage, where as in the model proposed by Banker and Natarajan (Oper Res 56: 48–58, 2008a), ordinary least squares (OLS) provides consistent estimation. This paper examines, compares, and contrasts the very different assumptions underlying these two models, and makes clear that second-stage OLS estimation is consistent only under very peculiar and unusual assumptions on the data-generating process that limit its applicability. In addition, we show that in either case, bootstrap methods provide the only feasible means for inference in the second stage. We also comment on ad hoc specifications of second-stage regression equations that ignore the part of the data-generating process that yields data used to obtain the initial DEA estimates.     

Nondiscretionary residential water use: the impact of habits and water‐efficient technologies

Several studies published in the last few decades have demonstrated a low price‐elasticity for residential water use. In particular, it has been shown that there is a quantity of water demanded that remains constant regardless of prices and other economic factors. In this research, we characterise residential water demand based on a Stone‐Geary utility function. This specification is not only theory‐compatible but can also explicitly model a minimum level of consumption not dependent on prices or income. This is described as minimum threshold or nondiscretionary water use. Additionally, the Stone‐Geary framework is used to model the subsistence level of water consumption that is dependent on the temporal evolution of consumer habits and stock of physical capital. The main aim of this study is to analyse the impact of water‐saving habits and water‐efficient technologies on residential water demand, while additionally focusing attention on nondiscretionary uses. This is informed by an empirical application using data from a survey conducted among residents of Brisbane City Council, Australia. The results will be especially useful in the design of water tariffs and other water‐saving policies.     

Turning values concrete: the role and ways of business selection in local currency schemes

Alternative consumption schemes require the selection of producers and traders according to criteria and through processes that should make alternative values concrete. The way values turn concrete is crucial for the effectiveness of such projects. This paper investigates the ways criteria and processes are defined and their real meanings and uses through the case of associative local currencies. Drawing on the framework of proximities, it analyses local currency schemes as combining proximities (geographical and non-geographical) and selection processes set up for providers wishing to join. Selection processes may be based on a charter, an approval committee and screening criteria. The objectives of the selection, its measures in principle, the way in which it is applied as well as the practical consequences are discussed. Even when charters and formal participatory schemes for selecting providers are established, proximities appear as the keystone of selection and trust.     

The Gravity Model and Trade Efficiency: A Stochastic Frontier Analysis of Eastern European Countries' Potential Trade

The opening up process of the eastern European countries is characterised by an increasing degree of trade integration with their Western neighbouring countries. Typically, the degree of East–West trade integration is assessed by comparing actual trade volumes with potential trade volumes projected from the gravity model parameters estimated for a group of countries that best represent normal trade relations. This approach, however, does not compare trade levels against a maximum level of trade feasible for the group of eastern European countries. This paper using a stochastic frontier specification of the gravity model is able to identify the efficiency of trade integration relative to maximum potential levels. The findings, based on a panel data set of bilateral exports from 17 Western European countries to the 10 new member states over the 1994–2007 period, indicate a high degree of East–West trade integration close to two‐thirds of frontier estimates, suggesting a low degree of trade resistances.     

Hyperinflation in a small open economy with a fixed exchange rate: A post Keynesian view

This paper examines the emergence of hyperinflation in a small open economy with a fixed exchange rate from a post Keynesian perspective. Three variables play key roles: distributive conflict, external debt, and expectations about the exchange rate. First, we propose a short-run Kaleckian macro model. Then, we study the long-run behavior of the model by endogenizing the price level and foreign indebtedness. We conclude that the existence of expectations about the nominal exchange rate is crucial to explaining the emergence of hyperinflation.     

Competing priorities as constraints in event travel careers

An event travel career is a potentially lifelong pattern of travel to events linked with an individual’s preferred leisure activity. This paper applies the concept of an event travel career to non-elite triathletes. For these active sport tourists, ongoing pursuit of an event travel career is arguably constrained by competing priorities that intervene between everyday life and their pursuit of an event travel career. In-depth interviews were conducted with 21 triathletes identified as pursuing an event travel career. Interpretive analysis revealed seven domains of competing priorities that could work to constrain their event travel career aspirations. These domains included familial relationships, domestic responsibilities, sociability, finances, leisure, wellbeing, and work/education. The seven competing priority domains were interrelated, and cyclical in their constraining effects. Data assisted in clarifying some defining characteristics of the event travel career concept, and challenged notions of leisure participation as entirely positive and fulfilling.
