Abstract We provide integral formulae for the Laplace transform of the entrance law of the reflected excursions for symmetric Lévy processes in terms of their characteristic exponent. For subordinate Brownian motions and stable processes we express the density of the entrance law in terms of the generalized eigenfunctions for the semigroup of the process killed when exiting the positive half-line. We use the formulae to study in-depth properties of the density of the entrance law such as asymptotic behavior of its derivatives in time variable.

AbstractSquare integrable and local martingales on a family of σ-fields generated by a basic jump process are shown to have representations as stochastic integrals with respect to a family of martingales associated with the jump process by using the idea of an innovation projection and the associated Lévy system, which is a local characterization of the jumps.

Skills development levies are increasingly being utilised to increase enterprise provided training in developing economies. South Africa is one such example. The impact of such incentive systems on the bottom-line of firms is a vital consideration in such programs. Particularly important are the economic conditions under which the incentive will stimulate participation by organisations. The transaction costs of participation must be taken into account: while a levy-grant system clearly creates a prima-facie incentive, it may be prohibitively expensive for some firms to enter the grant disbursement systems. Accordingly, through a simple model of the incentives for firms, the participation level of the firm under various types of levy systems is assessed. Non-monetary considerations are also considered. The implications for participation by firms, along with managerial and policy implications, are discussed.

Debate about the impact of modern technology on copyright law has become polarized—even harsh. Owners, with some justification, contend that copying has become too easy and that strong protections for their assets must be implemented in order to insure the continued production of creative work. Users respond, with some justification, that such strong protections place intolerable constraints on their rights to browse in digital space, of contemporary culture and fairly use copyright works. The form of the debate—with both sides raising valid problems and neither finding an easy solution inside the existing structure of copyright law—suggests a need to rewrite copyright to insure remuneration to copyright owners while still providing easy, cheap access for users.The most viable method for achieving such a goal is to institute a wide ranging system of levies on all devices and media that make it possible to quickly and easily copy protected copyright subject matter. In return for the payment of levies, owners would be required to allow users undisturbed access to their copyrighted works. This paper uses the sometimes checkered history of American copyright law as a vehicle for discussion of the problems technology presents to contemporary intellectual property law, the need for a levy system, the most significant requirements of a levy system and the nature of objections likely to arise to use of such a system.

The purpose of this research is to know and analyze hotel and restaurant tax policy in Surabaya. This research uses a quantitative approach, which is a research approach that many claimed by using numbers, ranging from data collection, interpretation of the data and the appearance of the results. Data analysis in this study using the analysis of the difference between the potential and the realization of tax and contribution analysis. Contribution analysis to find out how big contribution of hotel and restaurant tax to Revenue of Area of Surabaya. The result of research indicates that overall hotel and restaurant tax is still in the category of contributing greatly because the percentage of contribution above 4%. In addition, in order to minimize fraud on hotel and restaurant revenues to be paid for taxes, the online levy system should be included in the Surabaya Local Regulations on Local Taxes. The suggestion that can be submitted by the researcher is the government apply the policy in the form of Local Regulation about the procedure of online tax levy system for hotel and restaurant taxpayer so that any transactions that have been entered in the cash register automatically 10% of the transaction has been entered at the tax revenue. In addition, the relevant agencies (Tourism Office, Regional Revenue Service, Regional Finance and Asset Management Board) which handles hotel and restaurant tax in Surabaya should conduct a more solid coordination so that the tax target set is not too far with the realization of the existing tax .
