This rejoinder reflects an important step, for me, in a preoccupation with methodology that has provided me with many hours of enjoyable reading, not to mention anxiety. For me the ‘reality’ of the incommensurable nature of paradigms and acceptance of the legitimacy of a range of conceptual and philosophical traditions came late. As a constructionist I find myself on the ‘anything goes’ end of methodology choice. This paper and my main paper ought not to be read as a critique of ‘middle range’ theory, but as a critique of an important and necessary aspect of the way we all seek to inscribe facts and structure our writing. What follows is a reflection of the influence Bruno Latour’s writings have had on my ways of seeing and perhaps an unhealthy emphasis on the small things that combine to produce convincing arguments and ‘facts’.

This study examines whether the timing of adoption of the UK Statement of Standard Accounting Practice No. 20 'Foreign Currency Translation' depended on firms' financial characteristics. Consistent with US studies, we find that early adopters tended to be larger firms, and that variables, such as growth options, profitability, leverage and management payout, have strong predictive power. In general, the decision to adopt the Statement of Standard Accounting Practice No. 20 did not appear to adversely affect the profitability measures or dividend payout. Firms tended to adopt when the adverse economic consequences of the adoption were likely to be minimal. They also appeared to defer the adoption of the standard to influence their financial performance and, hence, to achieve certain corporate financial objectives. © 2006 AFAANZ.

We analyze detailed monthly data on U.S. open market stock repurchases (OMRs) that recently became available following stricter disclosure requirements. We find evidence that OMRs are timed to benefit non-selling shareholders. We present evidence that the profits to companies from timing repurchases are significantly related to ownership structure. Institutional ownership reduces companies' opportunities to repurchase stock at bargain prices. At low levels, insider ownership increases timing profits and at high levels it reduces them. Stock liquidity increases profits from timing OMRs.
The Long-Term impact of Business Support? - Exploring the Role of Evaluation Timing using Micro Data
Resumo:
The original contribution of this work is threefold. Firstly, this thesis develops a critical perspective on current evaluation practice of business support, with focus on the timing of evaluation. The general time frame applied for business support policy evaluation is limited to one to two, seldom three years post intervention. This is despite calls for long-term impact studies by various authors, concerned about time lags before effects are fully realised. This desire for long-term evaluation opposes the requirements by policy-makers and funders, seeking quick results. Also, current ‘best practice’ frameworks do not refer to timing or its implications, and data availability affects the ability to undertake long-term evaluation. Secondly, this thesis provides methodological value for follow-up and similar studies by using data linking of scheme-beneficiary data with official performance datasets. Thus data availability problems are avoided through the use of secondary data. Thirdly, this thesis builds the evidence, through the application of a longitudinal impact study of small business support in England, covering seven years of post intervention data. This illustrates the variability of results for different evaluation periods, and the value in using multiple years of data for a robust understanding of support impact. For survival, impact of assistance is found to be immediate, but limited. Concerning growth, significant impact centres on a two to three year period post intervention for the linear selection and quantile regression models – positive for employment and turnover, negative for productivity. Attribution of impact may present a problem for subsequent periods. The results clearly support the argument for the use of longitudinal data and analysis, and a greater appreciation by evaluators of the factor time. This analysis recommends a time frame of four to five years post intervention for soft business support evaluation.
