We examine the time‐series relation between aggregate bid‐ask spreads and conditional equity premium. We document that average marketwide relative effective bid‐ask spreads forecast aggregate market returns only when controlling for average idiosyncratic variance. This control allows us to document the otherwise elusive relation between illiquidity and returns. The reason is that idiosyncratic variance correlates positively with spreads but has a negative effect on conditional equity premium, causing an omitted variable bias. Our results are robust to standard return predictors, alternative illiquidity measures, and out‐of‐sample tests. These findings are important because they provide strong support for the literature's conjecture that marketwide liquidity is an important asset pricing risk factor.  相似文献

The possible existence of investor clientele groups has received little attention in the real estate finance literature. In this paper we develop a clientele model, which in equilibrium produces a clustering of investors by tax characteristics. Low-tax-bracket investors are concentrated in low-value rental housing that attracts rents which are high in relation to property values. On the other hand, only high-tax-bracket investors will be observed in high-value rental housing, and they charge rents that are low in relation to property values. An empirical model is specified and estimated using a cross section of investors in Australian private rental housing markets. Investor clienteles are detected among property investors, though there is a weak diversification effect indicating that clientele effects may be stronger among single property investors.  相似文献

Stop tank abuse     
Large volumes of fluids are processed or stored in tanks of all shapes and sizes and occupy a major portion of the landscape within our chemical plants and refineries. These tanks serve the industry very well but occasionally they suffer from improper design or abusive conditions and failures occur.  相似文献

A global transition towards diets increasingly dominated by ultra-processed foods (UPFs) has occurred in recent decades to the detriment of public health and the environment. This study aimed to examine long-term trends in the structure and market dynamics of the global UPF manufacturing industry as part of broader efforts to understand the drivers of this transition. Using diverse methods, metrics and data sources, we examined several dimensions (e.g., industry concentration and profitability) according to an adapted structure–conduct–performance model. We found that the global UPF manufacturing industry has evolved to become a major component of global food systems, with its longstanding dominant corporations becoming some of the system's largest accumulators of profit and distributors of capital. It follows that reversing the global UPF dietary transition will require structural and regulatory changes to ensure that population diets, and food systems more broadly, are not subordinated to the interests of powerful for-profit business corporations.  相似文献

The brewing industry has undergone profound structural and spatial change over the last 150 years. We examine how consolidation began in Victoria's brewing industry using a historical GIS approach. We argue that industry restructuring was shaped by four interlocking dynamics between 1870 and 1900: (1) structural economic change; (2) railway development; (3) technological innovation; and (4) regulatory reform. We show that the ebb and flow of these interacting dynamics generated a non-linear process of change. Similar to North America and Europe, the industry became highly concentrated. However, this process was complicated by local factors such as climate, economy, and distance.  相似文献

Protest in the gig economy has taken many forms and targets (platforms, customers and state officials). However, researchers are yet to adequately account for this diversity. We use a European survey of Upwork and PeoplePerHour platform workers to investigate worker orientation towards different forms of protest. Results reveal that worker anger, dependence and digital communication shape contention in the remote gig economy. Support for collective organisation is associated with anger at platforms as well as their dependence on the platform and communication with other workers. Individual action against clients is associated with anger and communication but not dependence. Support for state regulation is associated only with anger but not dependence or communication. We conclude that the relational approach entailed by Mobilisation Theory can aid explanation in the gig economy by shedding light on the dynamic process by which solidarity and dependence alter the perceived cost/benefits of particular remedies to injustice.  相似文献

When war broke out in Eastern Ukraine in 2014, the government of Ukraine failed to provide adequate defense to maintain its territorial integrity. In the wake of this government failure, several private volunteer efforts arose to meet popular demand for military action against Russian-backed Separatists. These volunteer battalions had to find alternative methods of aligning their incentives with the population wishing to be defended, and alternative methods of aligning the incentives of their leadership and their recruits. The success of these battalions depended on the potential for political careers and favors, the strength of reputation mechanisms in small communities, and the potential for loot and spoils. These factors shaped the size, characteristics, and activities of the volunteer battalions.
