Do business process reengineering projects payoff? Evidence from the United States

This paper examines whether implementation of business process reengineering (BPR) projects improve firm performance by analyzing a comprehensive data set on large firms in the United States. The performance measures utilized in the paper are labor productivity, return on assets, and return on equity. We show that firm performance increases after the BPR projects are finalized, while it remains unaffected during execution. We also find that functionally focused BPR projects on average contribute more to performance than those with a broader cross-functional scope. This may be an indication that potential failure risk of BPR projects may increase beyond a certain level of scope

Market Transparency in Business-to-Business (B2B) E-Commerce

Market transparency, in its most succint form, refers to the level of current trade information revealed to the public by market makers. We analyze the effect of market transparency on the outcomes of postedoffer style B2B markets under both stationary and non-stationary demand conditions. We find that sellers on average can extract significantly higher surplus than buyers, yet the difference decreases with increasing market transparency. Also, poor price-tracking ability of the posted-offer market after an external demand shock hurts buyers only. Seller profits are much less sensitive to the shock compared to buyer surpluses

We investigate the impact of Information Technology (IT) outsourcing on firm performance from several dimensions, including changes in labor productivity, improvements in financial and operational performance variables, and stock market valuation of IT outsourcing initiatives as measured by Tobin’s q. While our main objective is to better understand the economics of IT outsourcing, we also aim to contribute to the literature on the business value of IT in general. Our research contributes to the relevant literature from the following perspectives: (i) the change in the performance levels of firms due to IT outsourcing is measured against that of firms not outsourcing at all, (ii) panel data regression model is utilized in order to capture both cross-sectional and time-series differences among firms, (iii) the diversity of IT outsourcing initiatives is explicitly considered in the model, and (iv) a comprehensive data set covering the period between 1984 and 2007 is used.

Essays on the effects of information technology and the Internet on business environments

In this thesis, we investigate the effects of Information Technology (IT) and the Internet on business environments from three perspectives: the catalyst function of IT and the Internet in developing new business models, the enabler role of these technologies for emerging digital marketplaces, and their transforming effects on organizational measures such as productivity. The first essay analyzes a novel e-commerce model that reinforces loyalty on the Internet by giving customers a fraction of merchant firm\u27s stock for each purchase. We compare this model with online cash-back reward programs by developing a two-period duopoly model in which one of the firms gives customers a fraction of its stock and the other offers cash-back for each purchase. We find that stock-based e-loyalty programs are suitable for new start-up companies with low market shares, operating in large markets where consumers can easily switch between firms. The significance of our findings is that these conditions are available in Business-to-Consumer (B2C) markets, making them appropriate media to implement stock-based e-loyalty programs. The second essay introduces an emerging digital medium, called Donor-to-Organization (D2O) marketplace, which brings donors and fundraising organizations together in an electronic environment to facilitate finding a suitable match. We first investigate possible outcomes of using the D2O marketplace in traditional fundraising environments, and then develop a nonprofit duopoly model based on spatial competition. Using this model, we find analytical conditions under which implementing the D2O marketplace as a secondary channel in fundraising markets generates better outcomes. Finally, the last essay is an empirical study that examines whether the Business Process Reengineering (BPR) efforts of companies to leverage potential benefits of using IT in their functional units improve their productivity. We construct three productivity measures that are suitable for both the inter-organization and intra-organization comparisons. Using a firm-level data from two different economic sectors covering the period between 1985 and 2004, we employ a one-way panel regression model. Depending on the economic sectors of the firms, our results show that the reengineering efforts supported by IT improve some of these productivity variables during the period under consideration

Yumurtacı japon bıldırcınlarında diyete ilave edilen zeytin yaprağı özütü ve zarlı yumurta kabuğunun performans, yumurta kalitesi, kan biyokimyasal ve kemik parametreleri üzerine etkileri

This study was conducted to determine the effects of dietary supplementation of olive leaf extract (OLE), eggshell with the membrane (ESM), and the ESM that absorbed the OLE (OLE+ESM) on the performance, egg quality, biochemical, and bone parameters in laying Japanese quail. A total of 112 quail, being 45-day-old, were divided into 4 groups with 4 replicates. The quail were fed with four diets: i) basal diet ii) basal diet supplemented with 400 ppm OLE iii) basal diet supplemented with 2% ESM, and iv) basal diet supplemented with 2% ESM that absorbed with 400 ppm OLE. Egg weight was observed to be higher in the OLE group (P0.05). There was no statistical difference in tibia bone parameters (P>0.05). The lowest concentration of serum lactate dehydrogenase (LDH) was observed in control group (P<0.01). Serum uric acid level decreased in ESM group (P<0.01). OLE supplementation had limited impacts on quail nutrition. Consequently, while the individual usage of OLE and ESM did not show remarkable effects, the mixture of OLE and ESM has been found to positively affect the egg quality and performance parameters
