An Empirical Investigation of Market Structure, Efficiency, and Performance in Property-Liability Insurance

This study examines the relationships among market structure and performance in property‐liability insurers over the period 1992–1998 using data at the company and group levels. Three specific hypotheses are tested: traditional structure‐conduct‐performance, relative market power, and efficient structure (ES). The results provide support for the ES hypothesis. The ES hypothesis posits that more efficient firms can charge lower prices than competitors, enabling them to capture larger market shares and economic rents, leading to increased concentration. Both revenue and cost efficiency are used in the analysis, and this is the first study to use revenue efficiency in this type of analysis. The results for the sample period as a whole and by year are consistent. The overall results suggest that cost‐efficient firms charge lower prices and earn higher profits, in conformance with the ES hypothesis. On the other hand, prices and profits are found to be higher for revenue‐efficient firms. Revenue X‐efficiency is derived from activities such as cross‐selling and may rely heavily on the use of detailed information from customer databases to identify potential customers. The implications of this research are that regulators should be more concerned with efficiency (both cost and revenue) rather than the market power that arises from the consolidation activity taking place in insurance.     

Measuring revenue responses to tax rate changes in multi-rate income tax systems: behavioural and structural factors

This paper shows how income changes in response to changes in marginal income tax rates (MTRs) translate into tax revenue changes for the familiar multi-step income tax function used in many countries. Previous literature has focused on the relatively straightforward case of a proportional income tax or the top MTR only. The paper examines revenue responses at both the individual and aggregate levels, and it is shown that for individual MTRs within a multi-rate regime, simple expressions for tax revenue responsiveness can be derived that nevertheless capture the various behavioural and structural responses to income tax reforms involving changes to multiple rates and thresholds. Illustrations are provided using changes to the New Zealand income tax structure in the 2010 budget. This reduced all marginal tax rates while leaving income thresholds unchanged.     

CEO bonus compensation: the effects of missing analysts’ revenue forecasts

We investigate the incremental contract relevance of analysts’ revenue forecasts while controlling for earnings forecasts and find CEOs receive smaller bonuses when missing analysts’ annual and quarterly revenue expectations. Our results support the link between the value relevance of the revenue performance measure and the contract relevance of that measure. Further, we find revenue forecasts to be more contract relevant for CEOs of firms with high growth expectations, consistent with Rees and Sivaramakrishnan’s Contemp Acc Res 24(1):259–290, (2007) findings that growth firms receive a larger market penalty for missing revenue targets. Overall, our findings provide empirical support for the conjecture that compensation committees rely on information consistent with that conveyed in analysts’ revenue forecasts when contracting with management.     

A genetic algorithm approach to detecting temporal patterns indicative of financial statement fraud

This study presents a genetic algorithm approach to detecting financial statement fraud. The study uses a sample comprising a target class of 51 companies accused by the Securities and Exchange Commission of improperly recognizing revenue and a peer class of 339 companies matched on industry and size (revenue). Variables include 76 comparative metrics, based on specific financial metrics and ratios that capture company performance in the context of historical and industry performance, and nine company characteristics. Time-based patterns detected by the genetic algorithm accurately classify 63% of the target class companies and 95% of the peer class companies. Copyright © 2007 John Wiley & Sons, Ltd.     

An empirical study of auction revenue rankings: the case of municipal bonds

Using a novel dataset of 386 first‐price municipal bond auctions held in California, I perform counterfactual revenue comparisons, based on the theoretical result of Milgrom and Weber (1982). I show that the revenue in the second‐price auction is nonparametrically identified, and the counterfactual revenue in the English auction can be bounded in an informative way. These results form a basis for nonparametric estimation of counterfactual revenue differences. I find that the revenue gain from using the English auction would be in the range of 11%—19% of the gross underwriting spread, and that most of it would already be captured by using the second‐price auction. The recent explosive growth of Internet English auctions, administered by Grant Street Group, provides external support to the claim that auction design matters in this market.

Do the business cycle and revenue diversification matter for banks’ capital buffer and credit risk: Evidence from ASEAN banks

We examine the association of the business cycle and revenue diversification with the banks’ capital buffer and credit risk for a sample of banks from the Association of Southeast Asian Nations (ASEAN) region from 1998 to 2018, using 2847 banking firm–year observations. We find that ASEAN region banks react anticyclically in adjusting their capital buffer levels and credit risk. We find revenue diversification benefits and that banks, through revenue diversification, can reduce their credit risk while achieving capital savings when confronting economic downturns. Our results offer support for the Basel III accord. However, the relations revealed are somewhat moderated by the regulatory quality, competition, and phase of the business cycle encountered by ASEAN region banks.     

The Impact of Exchange Rate on Firm Performance: Evidence from Korean Firms

This article analyzes the role of exchange rate in explaining firm investment between 2006 and 2014, considering both export and import channels as possible factors along with other firm-level characteristics based on the Census on Establishments. Using the detailed information on exports and imports from the data, we are able to capture the cost and revenue channel more precisely compared to the previous existing literature. The empirical analysis shows that the export channel appears to be insignificant as opposed to conventional wisdom. However, the import channel is significant and shows that currency appreciation may not necessarily decrease a firm’s investment level.     

Hedging and liquidity

This article develops a model for evaluating alternative hedgingstrategies for financially constrained firms. A key advantageof the model is the ability to capture the intertemporal effectsof hedging on the firm's financial situation. We characterizethe optimal hedge. A wide range of alternative hedging strategiescan be specified and the model allows us to determine in eachcase if the hedging strategy raises or lowers firms value andby how much. We show that hedging firm value, hedging cash flowfrom operations and hedging sales revenue are not optimal. Thearticle highlights the fact that every hedging strategy comespackaged with a borrowing strategy which requires careful consideration.

The structure of the global reinsurance market: An analysis of efficiency,scale, and scope

We estimate economies of scale and scope as well as cost and revenue efficiency to explain the structure of the global reinsurance market, where large reinsurers dominate but both diversified and specialized reinsurers are competitive. The costs and benefits of size and product diversification are particularly relevant to the reinsurance industry, as risk diversification is central to the industry's business model. We find that reinsurers with total assets less than USD 2.9 billion exhibit scale economies, while those with total assets greater than USD 15.5 billion do not. Large reinsurers are characterized by high cost efficiency, while small reinsurers exhibit superior efficiency only when specialized. Large reinsurers also exhibit revenue scope economies when operating both life and nonlife reinsurance. Moreover, the evidence is in line with the efficient structure hypothesis: cost-efficient reinsurers can charge lower prices without sacrificing profitability.     

Capital Investment,Innovative Capacity,and Stock Returns

We study the dynamic implications of capital investment in innovative capacity (IC) on future stock returns, investment, and profitability by modeling the unique effects of IC investment on uncertain option generation/exercise and postexercise revenue. The model highlights the diverse effects of IC investment on expected returns in different postinvestment regimes and yields the novel prediction that, under the neoclassical assumption of nonincreasing revenue returns, IC investment is positively related to subsequent cumulative stock returns with a lag. The model also predicts a positive effect of IC investment on future investment and profitability. We find strong empirical support for these predictions.     

The Stability of Tax Elasticities over the Business Cycle in European Countries

We estimate short‐ and long‐run tax elasticities that capture the relationship between changes in national income and tax revenue. We show that the short‐run tax elasticity changes according to the business cycle. We estimate a two‐state Markov‐switching regression on a novel data set of tax policy reforms in 15 European countries from 1980 to 2013, showing that the elasticities during booms and recessions are statistically (and often economically) different. The elasticities of personal income taxes, corporate income taxes, indirect taxes and social contributions tend to be larger during recessions. Estimates of long‐run elasticities are in line with existing literature.     

对我国开征环境税的探讨

本文针对开征环境税的主要难点问题进行了分析,认为我国环境税应定位于直接污染税(或排污税);环境税与排污费相比,在法律、征管、收入使用、税费负担设计等层面都具有优势,其中,法律层面和征管层面的优势是排污费改税的主要推动力;自行申报、环保核定、税务征收的环境税征收模式相对具有可行性。     

经济下行叠加严峻疫情财税政策尤需注重提质增效

新型冠状病毒这一重大突发疫情年初起肆虐,给本已面临下行压力的我国经济叠加了一个典型的黑天鹅事件,需要财税政策加大支持与扶持力度,而持续且高强度的财税政策支持,正不断加剧财政收支紧张状况.在既要取得抗疫胜利,又要促进经济平稳健康增长,并化解当前经济内在的结构性矛盾的背景下,财税政策的设计与运用,必须基于成本效益原则、经济高质量发展理念、财税政策实际执行等视角更加注重提质增效.     

政府间收入分成与财政收入预算偏离

降低收入决算和预算之间的偏离程度是现代预算制度的基本要求,长期以来,中国政府的收入预算偏离一直处于高位运行状态。本文研究了政府间财政收入分成对收入预算偏离的影响。理论上,财政收入分成的上升会对下级政府产生减小财政压力和加大财政扩张两种截然相反的影响,前者会减少政府的收入预算偏离,而后者则会扩大收入预算偏离。运用市县层面加总的预决算数据,实证分析较为稳健地支持了财政压力机制:财政收入分成降低1个百分点,收入预算偏离会增加0.3个百分点。进一步分析表明,收入分成对预算偏离的影响相比市县级,在省本级层面不显著,并且其对预算偏离的影响会随着经济发展水平的上升而降低。本文研究的现实意义是,政府间收入划分的改革方案要兼顾长期稳定性与财力支持性,这对于降低收入预算偏离、推进现代预算制度建设和国家治理现代化具有重要作用。     

State regulation and the structure,conduct, efficiency and performance of US auto insurers

This research investigates the impact of regulation on state automobile insurance markets while controlling for other state insurance market characteristics that may be related to performance. Data for a large sample of insurers are analyzed. The results suggest that insurers in competitive and non-stringently regulated states may benefit from market power by charging higher unit prices, however insurers in these states are on average more cost X-efficient and cost X-efficient insurers charge lower prices and earn smaller profits. The empirical results also suggest that insurers in some rate regulated states are less revenue and cost-scale efficient than in competitive states.

Intergovernmental Fiscal Arrangements and Provincial Consumption Risk Sharing in China

This paper utilizes a panel data set on two major fiscal reforms in China—the fiscal contract system (FCS) in 1980-93 and the tax-sharing system (TSS) after 1994—to examine how the various aspects of intergovernmental fiscal arrangement affect the ability of the fiscal system to facilitate risk sharing. The high revenue decentralization and the proliferation of extrabudgetary revenue items in the FCS generally weakened the central government's ability to support interprovincial risk sharing. This situation was reversed in the TSS period. In addition, the effect of central-to-local transfer (transfer-in) and local-to-central transfer (transfer-out) on risk sharing was asymmetric in the sense that transfer-out enhances risk sharing but transfer-in does not.     

A Structural Model for Developing Countries' Manufactured Exports

A dynamic structural econometric model is developed to analyzemovements in manufactured exports and to capture lags in theadjustment to equilibrium. The model is estimated with pooledcross-section time-series data for a representative sample offifteen developing countries grouped according to their exportmarket power. The results suggest that prices, domestic productivecapacity, and external economic activity are critical determinantsof manufactured exports from developing countries. The structuralparameter estimates are used to infer the effects of changesin destination country income, distinguishing between the short-runand long-run export volume and export revenue effects. The resultsindicate that domestic economic policies that promote investmentand capacity in export-oriented activities are likely to playa key role in increasing foreign exchange earnings in developingcountries, even if growth in external demand is slow.
