What Does the CAPM Say About Operating Leverage?

We examine the issue of operating leverage and firm value. Johnstone (2020), in this issue, questions existing results which indicate that higher operating leverage results in lower firm value. We agree with Johnstone (2020) that this result is to be questioned and present a number of arguments which indicate that operating leverage is irrelevant to the valuation of the firm in the context of the CAPM model.     

A Primer on Global Environmental Change

This paper sets out the science behind global environmental change, defined by the US Global Change Research Act as ‘changes in the global environment (including alterations in climate, land productivity, oceans or other water resources, atmospheric chemistry, and ecological systems) that may alter the capacity of the Earth to sustain life’. We explain why there is still scepticism about the science in the business world and introduce eight gestalt shifts that are likely to change how executives think about environmental change and the threats and opportunities such changes present. The paper concludes with future research directions on business and global environmental change and outlines how the business case for investment in clean technology means that the transition to clean tech is inevitable.     

Global cities: A multi-disciplinary review and research agenda

Multinational enterprise (MNE) location decisions are central to international business (IB) scholarship and research shows that global cities are key MNE investment locations. Despite growing awareness of their importance to MNEs, most literature on global cities resides outside the IB domain. To provide IB scholars with a foundation to advance global city research, we conduct a multi-disciplinary review of top journal articles organized into three themes: the nature of global cities, MNE strategic decisions in global cities, and outcomes of MNE investment in global cities. We use this framework to synthesize findings, discuss theoretical implications, and provide future research directions.     

Understanding the dynamics of labor shares and inflation

Calvo-style models of nominal rigidities currently provide the dominant paradigm for understanding the linkages between wage and price dynamics. Recent empirical implementations stress the idea that these models link inflation to the behavior of the labor share of income. Ga?´ et al. (2001) argue that the model explains the combination of declining inflation and labor shares in Euro area. In this paper, we show that with realistic parameters, the canonical Calvo-style model cannot explain the joint behavior of inflation and the labor share in Europe. In addition, we show that the model fails very badly in sectoral data with consistently negative estimated coefficients on the labor share in a number of different inflation specifications. Indeed, the use of a traditional output gap measure proved more successful in terms of a positive relationship with inflation.     

Planetary boundaries: implications for asset impairment

Scientific findings support the existence of nine planetary boundaries which define a safe operating space for humanity and the conditions necessary to sustain human life. The declining state of the environment (4 of the 9 boundaries have been breached) creates significant risk factors for asset impairment. Risks result not only from environmental challenges and resulting resource constraints (e.g. limits to fossil fuel extraction and carbon constraints) but also changing technology landscapes and social expectations. This article is one of the first to discuss the implications of changes in planetary boundary conditions for asset impairment and recognising an impairment event and sets out an agenda for future research.     

Antonelli's analytical techniques: their exploitation to derive results in duality theory

Antonelli, over a hundred years ago, pioneered techniques of economic analysis which still can be usefully employed to provide apparently new insights in duality theory. This assertion is demonstrated through the applications of these techniques to derive specific results in duality theory. These applications allow an apparently new derivation of the equality between the partial derivative of the expenditure function, with respect to the price of some good, and the compensated level of demand for this good. In addition, use of Antonelli's analytical techniques reveals links between certain results in duality theory that, apparently, have not been noticed before in the relevant literature.
