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

The Japanese disclosure system of consolidated statements was introduced in 1977 and extensively revised in 1997. The role of the bureaucracy has been significant in these developments and seems to be part of Japan's closed culture. However, other explanations could also be applied. In particular, although Japanese firms opposed such disclosures on the basis of preparation costs, the Japanese government had to modernize the disclosure system, including consolidation, in order to develop the securities market regardless of an individual company's interests.  相似文献

Recursive formulae are derived for the evaluation of the moments and the descending factorial moments about a point n of mixed Poisson and compound mixed Poisson distributions, in the case where the derivative of the logarithm of the mixing density can be written as a ratio of polynomials. As byproduct, we also obtain recursive formulae for the evaluation of the moments about the origin, central moments, descending and ascending factorial moments of these distributions. Examples are also presented for a number of mixing densities.  相似文献

After the Second World War, during the neutralization of the controlled economy of wartime Japan, a design for a Corporate Accounting Law was elaborated by the Investigation Committee on the Business Accounting System. The Investigation Committee tried to establish not only new business accounting standards but also a central and independent administrative organ of corporate accounting regulation on the basis of the Corporate Accounting Law. The Corporate Accounting Law was expected to lay the legal foundation of the new corporate accounting regulation regime in Japan. Nevertheless, even though the original design of the fundamental accounting law was never realized, it should be considered the starting point for our understanding of external accounting history in post-war Japan.  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 trading station or factory maintained by the Dutch East India Company (VOC) was Japan's sole window on the Western world during most of the Tokugawa period (1600-1868). While many aspects of the factory's role in Dutch/Japanese cultural exchange have been researched little is known in the West of the accounting at the factory. This paper considers the possibility that double-entry bookkeeping employed by the Dutch may have been diffused to the Japanese. The available evidence is synthesized after considering the accounting system in the Dutch factory.  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

Both the US and UK governments attempted desperate measures during World War I in an effort to maintain wartime production levels of necessary commodities and to allow for their economical purchase by the military. Loft (1986a, 1986b, 1990) has studied the British experience in depth, concluding that UK cost accountancy 'came into the light' as a result. It might be expected that similar developments would have occurred in America with the activities of the War Industries Board. In both countries, national associations were established in the immediate aftermath of the war to promote the professional standing of cost accountants. This paper utilizes archival materials in an effort to investigate whether US cost accountancy was developing more sophisticated costing techniques as Loft has claimed for the UK, or whether practitioners in this country were left 'still cursing the darkness'. Our findings suggest that cost accountancy developed in parallel fashion in both countries. US and UK cost accounting professionalism was dominated by the presence of leading financial accounting practitioners, and in both countries the movement towards more sophisticated costing techniques was gradual rather than dramatic.  相似文献

Share premiums now constitute a substantial proportion of UK company equity but rarely featured on nineteenth century company balance sheets. This paper discusses when and why this changed and why the definition of the share premium account as company capital took nearly a century to reach the statute books. From 1855 to 1948 any surplus above par on issued shares could be treated at the directors' discretion, including appropriation for the payment of dividends. This freedom was removed in the Companies Act 1948 (s. 56), after the Cohen Committee recommended that share premiums should normally be treated as share capital and employed in a very limited range of transactions. The paper outlines the accounting and legal history of the share premium account and argues that the growth of share premiums was due to a tax avoidance loophole, open from 1889 to 1973, which permanently changed company practice on share issues after 1920. The effect of legal restrictions on the use of the share premium account is also addressed. One possible future consequence of the loss of economic significance of the nominal value of a share is the total abolition of both this and the share premium account by adoption of no par value (npv) shares, a change which has recently been adopted in Australia and is again under consideration in the UK.  相似文献

This paper aims to show two things. The first is how Japanese culture has contributed to the development of Japanese cost accounting history. The second is to reveal the research possibilities of cost accounting history. This paper also reviews the salient features of several important examples of these aspects of cost accounting practice in Japan. It therefore explores, through some practical illustrations, how and why Japanese cost accounting differs from that found in the West.  相似文献
