Labor Market Effects of Spatial Licensing Requirements: Evidence from CPA Mobility

We exploit the staggered introduction of CPA Mobility provisions in the United States to study the effects of spatial licensing requirements on the labor market for accounting professionals. Specifically, we examine whether the removal of licensing‐induced geographic barriers affects CPA wages and employment levels, as well as the pricing and quality of professional services. We find that, subsequent to the adoption of CPA Mobility provisions, wages of accounting professionals decrease, whereas employment levels are unaffected. The documented wage effect stems from smaller CPA firms, is more pronounced for CPAs holding senior positions, and persists over time. We also find that service prices decline and that this effect is concentrated in local CPA firms. Moreover, we document that the increased wage and price pressure is not associated with deteriorating service quality. Collectively, our results suggest that the removal of occupational licensing barriers has sizable effects on labor supply and service prices. Our findings inform the current regulatory debate on occupational licensing.     

Optimal Income Taxation and Public Good Provision with Endogenous Interest Groups

This paper studies public goods provision when agents differ in earning abilities as well as preferences. Heterogeneity in skills makes redistribution desirable and generates an equity-efficiency trade-off. If tax revenues are devoted to a public good, this trade-off is affected in such a way that income transfers are less desirable. High-skilled individuals thus have an incentive to exaggerate their preferences for public goods. Analogously, low-skilled individuals lobby against public good provision. A requirement of collective incentive compatibility eliminates these biases. It implies that income transfers are increased whenever a public good is provided and are decreased otherwise.     

Livelihoods after Land Reform in Zimbabwe: Understanding Processes of Rural Differentiation

This paper explores the consequences of Zimbabwe's land reform for the dynamics of differentiation in Zimbabwe's countryside, reporting on the results from a 10‐year study from Masvingo province. Based on a detailed analysis of livelihoods across 400 households at 16 sites, the paper offers a detailed typology of livelihood strategies, linked to a class‐based analysis of emerging agrarian dynamics. The paper identifies a significant and successful ‘middle farmer’ group, reliant on ‘accumulation from below’ through petty commodity production, existing alongside other worker‐peasants and the semi‐peasantry, whose livelihoods remain vulnerable, with prospects for accumulation currently limited. In addition, there are others who are ‘accumulating from above’, through patronage and corruption. While small in number, this group has significant political and economic influence, and is embedded in powerful alliances that have fundamental impacts on the wider political–economic dynamics. To conclude, the economic, social and political implications of the emerging patterns of differentiation in Zimbabwe's countryside are discussed.     

The Influence of Nonaudit Service Revenues and Client Pressure on External Auditors' Decisions to Rely on Internal Audit*

This paper investigates how external auditor provision of significant nonaudit services and client pressure to use the work of internal audit influence external auditors' use of internal auditors' work. More specifically, we study how external audit evidence gathering choices are influenced by nonaudit fees and client pressure. Our research is motivated by an observation that the magnitude of nonaudit services provided to audit clients introduces the risk that client management may leverage its position with the external auditor and potentially affect the audit process. We address this issue by extending prior research and focusing on the importance of various explanatory variables, including nonaudit service revenues, client pressure, internal audit quality, and coordination, to the external auditor's decision to rely on the work of internal audit. We use data primarily obtained through surveys completed by internal and external auditors. The survey responses represent 74 separate audit engagements. Our findings reveal that when significant nonaudit services are not provided to a client, internal audit quality and the level of internal‐external auditor coordination positively affect auditors' internal audit reliance decisions. However, when the auditor provides significant nonaudit services to the client, internal audit quality and the extent of internal ‐ external auditor coordination do not significantly affect auditors' reliance decisions. Furthermore, when significant nonaudit services are provided, client pressure significantly increases the extent of internal audit reliance. Thus, external auditors appear to be more affected by client pressure and less concerned about internal audit quality and coordination when making internal audit reliance decisions at clients for whom significant nonaudit services are also provided.     

Bank Size and Household Financial Sentiment: Surprising Evidence from University of Michigan Surveys of Consumers

We analyze comparative advantages/disadvantages of small and large banks in improving household financial sentiment. Matching University of Michigan Surveys of Consumers household sentiment data with local banking market data from 2000 to 2014, we find surprising results—large banks have significant comparative advantages in boosting such sentiment. The findings apply across demographic groups, market types, and time periods, and are robust to different measurements and econometric methods. We contribute to the literatures on bank specialness, benefits and costs of small and large banks, household sentiment, and real effects of banking. We conjecture about the drivers of the findings, and discuss policy implications.     

QUANTIFYING MARKET POWER IN THE GERMAN WHOLESALE ELECTRICITY MARKET USING A DYNAMIC MULTI‐REGIONAL DISPATCH MODEL*

This paper quantifies the degree of market power in the German wholesale electricity market. A dispatch model simulates competitive marginal costs. In addition to common input factors like plant capacities, fuel prices and load structures, the model also incorporates international power exchange and dynamic effects like start‐up costs and hydro storage plant dispatch. The simulated prices are subsequently used as a benchmark for observed electricity prices. The analysis reveals significant market power in the German electricity market, mainly exhibited during peak periods. Producer surplus is also increased significantly due to strategic behavior.
