An economic analysis of sheep flock structures for mixed enterprise Australian farm businesses

A strategic question facing many mixed enterprise broadacre farm businesses in Australia is, ‘What sheep flock size and structure is most profitable to complement the farm’s cropping enterprises?' This study answers this question for a typical large mixed enterprise farm business in a key production region of Australia. Whole‐farm bioeconomic modelling, combined with broad‐ranging sensitivity analysis, is used to examine the profitability of different sheep flock structures and sizes. We find the most profitable flock structure is to run Merino ewes and turn off finished Merino or first‐cross lambs. The profitable selection of these flocks is robust to commodity price variation but does require the farmer to give more attention to sheep management. The correct choice of flock structure greatly adds to farm profit. A farm based on cropping and a self‐replacing Merino flock using surplus ewes for first‐cross, meat lamb production earns 33 per cent more profit than a similar farm that runs a traditional self‐replacing Merino flock that emphasises wool production. Of far less importance than flock structure, as a source of additional profit, is to increase flock size or adjust cropping intensity.     

Distance to Growing Markets and Sub‐Saharan African Exports*

Abstract: A typical person in sub‐Saharan Africa is a long way from world markets and is further from world markets now than in 1980. This partly reflects slower growth within Africa than for the world as a whole. Despite slower growth in Africa, African exports have become increasingly regionalized. By 2005, a country in Africa typically exported more than twice as much to a country in its own region as would be expected based on economic size and bilateral distance. This regionalization was not present in the early 1980s and has become stronger over time. We find evidence of positive neighborhood effects through exports, but sub‐Saharan countries benefit less from growth in their own region than this typical relationship indicates. Given the small share of exports destined to their neighbors, low‐income countries in sub‐Saharan Africa experience relatively modest export growth from growth in the region. These factors imply that African countries are unlikely to pull each other out of poverty and a regional focus may be less effective than a focus on countries outside of the region.

The determinants of reserves disclosure in the extractive industries: evidence from Australian firms

This paper examines the determinants of reserves disclosure (RD) in the Australian extractive industries. Our regression results indicate that RD are positively associated with variables relating to corporate governance, foreign listing, existence of reserves in foreign jurisdictions, pledging of reserves in debt covenants, leverage and external (Big 4) auditor, after controlling for firm size, subindustry, shareholder concentration and development/production stage. Additional regression testing shows that the existence of reserves in foreign jurisdictions is the most important determinant of RD in Australia. This paper contributes to a better understanding of the extent and rationale behind the RD practices of Australian resource firms.     

Corporate social responsibility reports: topic analysis and big data approach

ABSTRACT

This paper performs topic modeling using all publicly available CSR (Corporate Social Responsibility) reports for all constituent firms of the major stock market indices of 15 industrialized countries included in MSCI Europe for the sample period from 1999 to 2016. Our text mining results and LDA analyses indicate that ‘employees safety’, ‘employees training support’, ‘carbon emission’, ‘human right’, ‘efficient power’, and ‘healthcare medicines’ are the common topics reported by publicly listed companies in Europe and the UK. There is a clear sector bias with industrial firms emphasizing ‘employee safety’, Utilities concentrating on ‘efficient power’ while consumer discretionary and consumer staples highlighting ‘food waste’ and ‘food packaging.’ To produce these results, we used a battery of python code to organize the hundreds of reports downloaded from Bloomberg and the internet, the latest R-algorithm to estimate LDA (Latent Dirichlet Allocation) model and the LDAvis interactive tool to visualize and refine the LDA model.     

The determinants of shareholder value in European banking

This paper examines the determinants of shareholder value creation for a large sample of European banks between 1998 and 2005. As the recent turmoil in global banking systems has illustrated, bank performance can have a substantial influence on efficient capital allocation, company growth and economic development. We use a dynamic panel data model where the bank’s shareholder value is a linear function of various bank-specific, industry-specific and macroeconomic variables. We show that shareholder value has a positive relationship with cost efficiency changes, while economic profits are linked to revenue efficiency changes. Credit losses, market and liquidity risk and leverage are also found to substantially influence bank performance. These results are robust to a variety of different model specifications.     

The Roles of Some Key Stakeholders in the Future of Accounting Education in Australia

This article explores the role of institutional and systemic leadership in changing higher education in accounting in Australia. In particular, it discusses the roles of the Australian Learning and Teaching Council, the Australian Business Deans' Council Teaching and Learning Network, and the professional accounting bodies in meeting the challenges confronting accounting education in the tertiary sector today and in the coming years. The intersection of these leadership roles is exemplified in an accounting discipline research project that explores the critical non-technical skills stakeholders require in graduate students and discusses stakeholders' roles and responsibilities in their development .
