We propose a fully Bayesian approach to non-life risk premium rating, based on hierarchical models with latent variables for both claim frequency and claim size. Inference is based on the joint posterior distribution and is performed by Markov Chain Monte Carlo. Rather than plug-in point estimates of all unknown parameters, we take into account all sources of uncertainty simultaneously when the model is used to predict claims and estimate risk premiums. Several models are fitted to both a simulated dataset and a small portfolio regarding theft from cars. We show that interaction among latent variables can improve predictions significantly. We also investigate when interaction is not necessary. We compare our results with those obtained under a standard generalized linear model and show through numerical simulation that geographically located and spatially interacting latent variables can successfully compensate for missing covariates. However, when applied to the real portfolio data, the proposed models are not better than standard models due to the lack of spatial structure in the data.  相似文献

This paper examines the way two accounting techniques, namely depreciation and foreign exchange, were deliberated on, between 1870 and 1900, in an Indian jute company whose shareholders resided in the UK. The arena for these deliberations was the conflictual relationship between controlling and non-controlling shareholders as to how best to account for depreciation and foreign exchange especially when the particular accountings affected distributional issues such as the dividend decision. The purpose of this paper is to analyse and explain the processes by which a company's accounting practices emerge and develop as a contest between different interests. Accounting framed the parameters of the deliberations and provided the language of power and dissent. The paper uses a rich archive that includes narrative and accounting material.  相似文献

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.  相似文献

We introduce an expected utility approach to price insurance risks in a dynamic financial market setting. The valuation method is based on comparing the maximal expected utility functions with and without incorporating the insurance product, as in the classical principle of equivalent utility. The pricing mechanism relies heavily on risk preferences and yields two reservation prices - one each for the underwriter and buyer of the contract. The framework is rather general and applies to a number of applications that we extensively analyze.  相似文献

Historically, Japanese accounting standards have been quite distinct from International Accounting Standards (IASs) which have been perceived as being modelled on British-American accounting standards. However, in the 1990s, after the publication of E32 in 1989 and the IASC-IOSCO Agreement in 1995, the Business Accounting Deliberation Committee (BADC), the standards-setting body in Japan, has pursued a policy of harmonization with IASs. Accounting standards relating to consolidated financial statements of companies that make cross-border offerings of securities or operate worldwide are being revised drastically. This paper focuses on the development of international accounting harmonization and its impact on Japan.  相似文献

We investigate the diversification benefits of energy assets in the setting of commodity financialization using data on crude oil futures and Sector ETFs (SPDRs). Correlations between commodities and financial assets increased during the post-Commodity Futures Modernization Act (CFMA)/commodity bull cycle period, resulting in lower benefits of diversification. However, we find that conditional correlations between crude oil futures and sector ETFs meaningfully increased only since the 2008–09 financial crisis. The results therefore suggest that the financial crisis, rather than CFMA regulation, explains changes in the diversification benefits of commodities. Moreover, we find that oil futures returns are less correlated with SPDRs than with the S&P index. Thus, energy futures, and crude oil in particular, offer the potential for diversification benefits in sector-style investing.  相似文献

The Japanese shipping industry adopted European-style book-keeping in the 1870s. Before 1937, there were few regulations on accounting practices in Japan and we can observe their natural evolution at the Nippon Yusen Kaisha (NYK). NYK, which prospered to become a blue-chip company, developed its accounting techniques in asset valuation exploiting a policy that income and expense from selling securities or vessels should not go directly to the profit and loss account. Asset revaluations were undertaken not to reflect market value but to implement accounting strategy.  相似文献

Numerous empirical studies confirm that the stock market reacts negatively to the announcement of an equity issue. Yet some seasoned offerings occasion a positive market response. Studies investigating the differentiation of positive from negative responses should contribute to our understanding of both market and firm behaviour. In addition, few studies to date have examined market responses in other institutional and/or geographical settings. A sample of 95 open offerings by Irish firms between 1987 and 1994 is investigated and, surprisingly, a neutral market response is discovered. The hypothesis that a positive market response is due to a firm's growth opportunities is tested. The intuition underlying this growth opportunity hypothesis is that investors perceive the potential gain in growth opportunities and willingly fund such investments. The Irish evidence supports this hypothesis. It is conjectured that the lack of a long-term debt market in Ireland may explain these results.  相似文献

This article defines the case for treating management history as a discrete subject area, although one closely related to business, accounting, labour, and industrial history. It seeks to concentrate on the nature, process, and practice of management as an activity within the organization, and to argue that it is important that modern British managers understand the intellectual and cultural roots of their profession, since without these they will tend to be swayed by short-term management 'fads'. Within the broad topic there are several identifiable sub-areas for potential exploration, including the comparative historical development of management between different countries, management institutions, managerial careers and labour markets, management structures, management skills, and management thought and theory.  相似文献

In the paper we consider an endowment insurance contract with a twelve months maturation time. Using the majorization order and Schur-convex functions we derive upper and lower bounds of the premium, the death and survival benefits for a hetrogeneous population of insureds. The bounds are obtained for the exponential, Balducci, and linear approximations.  相似文献

The phrase 'accepted accounting principles' underlying financial statements is a forerunner of today's accounting standards. Here, it is argued that history shows that the term 'principles' is often most vague in debates on the development of those standards. The reasons for and consequences of that vague use are varied and complex. This article provides insights not highlighted in earlier analyses of the periods reviewed. While debates like the rule- versus principle-based standards are set up as two-dimensional, the many dimensions of accounting often allow argument to be easily diverted. The debate/argument thus remains unresolved. For progress to be achieved in the establishment of accounting standards the many dimensions of accounting must be acknowledged and attempts to divert debate minimized. Those with a stake in the development of accounting standards need to consider the total scene of the related accounting. In a particular debate, dimensions under scrutiny must be stated, with any others in that total scene being acknowledged even if kept constant.  相似文献
