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.     

The effects of public spending externalities

We conduct a positive analysis on the effects of ‘externalities’ produced by government spending. To this effect, we estimate, using U.S. data, an RBC model with two salient features. First, we allow government consumption to directly affect the marginal utility of consumption. Second, we allow public capital to shift the productivity of private factors. We provide an identification analysis that supports the strategy adopted for estimating the parameters governing these two channels. On one hand, private and government consumption are robustly estimated to be substitute goods. Because of substitutability, labor supply reacts little to a government consumption shock, so the estimated output multiplier is much lower than in models with separabilities. On the other hand, our results point towards public investment being ‘unproductive’.     

Retail channel price discrimination

This paper examines price differentials of identical items across retail channels. Many consumer packaged goods are sold through both grocery and drug stores. Liquor is unique in that in much of the country there is a third retail channel of distribution, liquor stores. If consumers in each retail channel differ in their willingness to pay for certain items, then sellers can exploit those differences and charge different prices for the same items in each channel. We examine a unique data set of pooled cross sectional retail scanner data on wine to test whether sellers use retail channel to identify heterogeneous consumer market segments and engage in price discrimination. We begin by presenting a model of price discrimination by retail channel along with behavioural assumptions regarding shoppers in each channel. Next we examine sales by retail channel and find persistent price differentials for the same item across retail channel after controlling for sample selection bias and seasonality. Lastly, we estimate the price elasticity of demand correcting for endogeneity and find differences across channel consistent with the price differentials. The extent of price differential, however, differs significantly with respect to price point.     

The importance of farmer education in South Australia

There is a significant challenge involved with balancing food security at local and global levels whilst mitigating the environmental and social consequences of the historically productivist agri-food system. This work will address the importance of education in the South Australian agricultural sector as a tool to maximise beneficial outcomes. The results of a blended method research project, which involved farmers and governance stakeholders in South Australia, are presented as empirical evidence highlighting the positive roles that formal education, in particular university education, have in regard to increasing sustainability. It was found that higher levels of formal education contributed to farmers being more likely to prioritise the socio-environmental outcomes of their agricultural land use. There was also a dramatic reduction in farmer concerns with government support mechanisms as education levels went from secondary or less, through to vocational qualifications, and finally university degrees. Interviews with agricultural governance stakeholders emphasised the role of education in building the adaptive capacity of farmers, and the subsequent positive outcomes for the future development of the South Australian agricultural industry. These results suggest that further education provides farmers with the capacity to compete effectively in a liberalised economy.     

Knowing your boundaries: Integration opportunities in international professional service firms

This study presents three different business models (continuous, repetitious, and unique) identified in international professional service firms that pursue a transnational strategy. These business models have varying opportunities for global integration. We extend the integration–responsiveness framework by offering a framework for analyzing how to balance global integration with local responsiveness when pursuing a transnational strategy. By identifying the content, structure, and governance transactions of the three business models, we can determine when to pursue headquarters-initiated global integration and when to choose strategies that ensure local responsiveness and subsidiary competitiveness in local markets.     

CONVERTIBLE BOND PRICING MODELS

Convertible bonds are an important segment of the corporate bond market, with worldwide outstandings approaching US$235 billion. Simple pricing models value a convertible bond as being equivalent to a straight bond with an embedded option that enables the bond holder to convert to a specific amount of common stock. The straight bond is subject to both interest rate and credit risk, whereas the option to convert is dependent on the underlying stock price, which exposes the convertible bond holder to equity risk. The complexity of these features means that convertible bonds tend to be treated casually in major derivatives and corporate finance textbooks. This paper presents a survey of the theoretical and empirical aspects of convertible bond pricing. The limitations of these studies are highlighted to identify those areas of research that may improve the valuation process and facilitate the application of these securities for corporate financing.     

Theoretical,empirical, and operational models in hotel location research

This paper aims to review past literature on hotel location models and evaluate the state of the art, as well as set out future directions. This study divides hotel location models into three major categories: theoretical models, empirical models, and operational models. Four theoretical hotel location models are reviewed and discussed, including the tourist-historic city model, the mono-centric model, the agglomeration model, and the multi-dimensional model. Based on previous literature, six empirical models and three operational models of hotel location are elaborated. Furthermore, some challenges related to hotel location studies are discussed, and future research directions are provided. In particular, we advocate the development of more sophisticated hotel location models and the use of Geographic Information System (GIS) in hotel location analysis.     

Are we all on the same boat? The challenge of adaptation facing Portuguese coastal communities: Risk perception,trust-building and genuine participation

The Portuguese coast is experiencing severe erosion and loss of beachfront, processes which are expected to become worse with climate change impacts. These additional alterations are beginning to show at a time when financing for conventional coastal protection is no longer guaranteed at scales of investment which are likely to be required if future coastlines are to be maintained. This paper looks at how residents and key stakeholders of three coastal communities in Portugal perceive such possible changes, how far they judge and trust current coastal management, and how they perceive their current participation and foresee future forms of involvement on adaptive coastal change. The evidence from these surveys and interviews suggests that there is a strong commitment in each location to maintaining current levels of coastal protection, and to preserving the integrity of local societies and economies, even though there is also recognition that adaptation in some form will eventually be required. However, our research reveals that there is not yet sufficient trust between coastal stakeholders, especially towards public institutions and policies, for any degree of progressive coastal adaptation to take place. Building trust in creative learning processes of progressive adaptation could lead to improved science and participation along with a meaningful dialogue over cooperative coastal planning and financing. The research undertaken for this paper lays the groundwork for such a process of trust-building to begin.     

NONPARAMETRIC AND SEMIPARAMETRIC PANEL DATA MODELS: RECENT DEVELOPMENTS

In this paper, we provide an intensive review of the recent developments for semiparametric and fully nonparametric panel data models that are linearly separable in the innovation and the individual-specific term. We analyze these developments under two alternative model specifications: fixed and random effects panel data models. More precisely, in the random effects setting, we focus our attention in the analysis of some efficiency issues that have to do with the so-called working independence condition. This assumption is introduced when estimating the asymptotic variance–covariance matrix of nonparametric estimators. In the fixed effects setting, to cope with the so-called incidental parameters problem, we consider two different estimation approaches: profiling techniques and differencing methods. Furthermore, we are also interested in the endogeneity problem and how instrumental variables are used in this context. In addition, for practitioners, we also show different ways of avoiding the so-called curse of dimensionality problem in pure nonparametric models. In this way, semiparametric and additive models appear as a solution when the number of explanatory variables is large.
