Are the self-employed really jacks-of-all-trades? Testing the assumptions and implications of Lazear’s theory of entrepreneurship with German data

Using a large representative German data set and various concepts of self-employment, this paper tests the “jack-of-all-trades” view of entrepreneurship by Lazear (Am Econ Rev 94(2): 208–211, 2004). Consistent with its theoretical assumptions we find that self-employed individuals perform more tasks and that their work requires more skills than that of paid employees. In contrast to Lazear’s assumptions, however, self-employed individuals do not just need more basic but also more expert skills than employees. Our results also provide rather limited support for the idea that human capital investment patterns differ between those who become self-employed and those ending up in paid employment.     

Emerging Markets and the Global Monetary System: The Challenge of Rising Inflation

While spillovers of the present financial turmoil in mature economies to emerging economies have so far largely been contained, the monetary policy implications of the financial turbulence present a challenge to the approach pursued by emerging markets in integrating into the global monetary system following the crises of the mid to late 1990s. Specifically, the period of a smooth coexistence between meeting inflation targets and maintaining a high degree of exchange rate stability is likely to come to an end. * At the time of writing this paper, the second author was an advisor at the Deutsche Bundesbank on secondment from the European Central Bank.

TRANSFER PRICING IN A DEPOSIROTY FINANCIAL INTERMEDIARY: PROOF OF A CONJECTURE FOR THE CASE OF NORMALLY-DISTRIBUTED CASH WITHDRAWALS*

In an earlier paper, a source of gains from the centralization of a financial intermediary's management of its cash reserves was conjectured. This note presents a mathematical proof of the conjecture for the special case of normally-distributed cash withdrawals.     

The effect of self-confidence and anxiety on risk reduction strategies for an innovative product

This research investigated consumer modes of information seeking as a means of reducing uncertainty for a high risk innovation. Measures of consumers' generalized and specific selfcondidence along with anxiety were taken to study their mediating effect on consumer's tendency to seek any of six information sources. Subjects completed a 20 item behavioral differential designed to measure the tendency to seek different sources. The design used was a 2×2×2 ANOVA. The sample was drawn from a middle, upper middle class, white suburban civic club. The results show that specific self-confidence was the most important variable in explaining the tendency to seek information about a microwave oven. The two most favored information sources were the impersonal independent (Consumer Reports type of magazine) and the subject's own observation and experiences. There was some tendency to use interpersonal sources, but the impersonal independent and observation/experience were favored.

ACCOUNTING COURSES AND PROFESSIONAL FUNCTIONS*

In Australia, people performing accounting functions may have undertaken a course at a university, CAE, or technical college. This study is addressed to the rationale for this multiplicity of courses by seeking to determine whether there are different outcomes, such as professional functioning and salary, among graduates from these different courses. A specially devised questionnaire was developed to determine the degree of professionalism in late 1979 of accounting graduates from some Sydney and Melbourne universities, CAEs (UG1 bachelor degree and UG2 diploma courses), and technical colleges from the following years: 1970, 1974, 1976 and 1978. Limitations such as sample size prevent definitive answers. It was found that degree of professionalism and salary were related to attendance pattern, years of accounting experience before course completed, and years of accounting experience after course completed, but that the relationships with accounting course studied are low. Data counceming the mean percentage time spent on professional, technician, and other functions are provided.
