Estimating an Endogenous Growth Model with Public Capital and Government Borrowing: U.S. and Germany 1960–1995

The paper presents and estimates an endogenous growth model with publiccapital and government borrowing. Government behavior (tax rates, spending andborrowing) does not follow optimizing rules but is restricted by two fiscalregimes (rules). In the strict fiscal regime government borrowing is used forpublic investment only. In the less strict regime it can also be used forpublic investment and to a certain degree for the debt service. The growthrate differs in our model variants according to which rule is adopted.Moreover, the growth maximizing income tax rate is different from zero. Forthe two relevant fiscal regimes, which correspond roughly to the cases of theU.S. and Germany, the model is estimated by employing time series data from1960.4 to 1992.1 and 1966.1 to 1995.1 respectively. The results suggest anexplanation for the different time paths of economic variables in the Americanand German economies in the post-war period.     

How Should the Chinese Government Invest R&D Funds: Enterprises or Institutions?

With the rapid increase of the government R&D investment in China, the efficient optimization of the R&D investment areas of the Chinese government significantly influences regional innovation productivity and economic growth in the long run. By expanding the R&D-based growth model and using empirical analysis, this paper discusses the optimal combination for the government to coordinate its R&D expenditure as productive public investment in various sectors, under the condition of promoting long-term economic growth, is discussed by considering the aspects of capability for independent innovation, the development capability for basic knowledge, and the absorption capability for the technique. Results are as follows. (1) The level of production efficiency of enterprises, such as the capability for independent innovation, the development capability for basic knowledge, and absorption capability, influences the inclination of the government to invest in enterprises and institutions. When an enterprise has a high production efficiency level, technological level A, and knowledge storage B, increased investment from institutions to the enterprise can significantly promote regional economy growth. Otherwise, the government should increase R&D investment in institutions. (2) The government R&D investment in institutions can indirectly promote economic growth through the promotion of human capital and the understanding and absorption capacity of external knowledge, independent innovation capability, and basic knowledge development capability of enterprises. This paper may help the government to create appropriate policies with higher efficiency in R&D investment, and promote technical progress and economic growth in China.     

Near optimal regional investment using a simultaneous equation economic model

A region seeking development objectives should attempt to schedule public investment optimally between human resources and physical infrastructure. A regional growth model and a suitable objective function are presented. It is desired to calculate both the optimal public investment for nominal parameter values and the sensitivity of the optimal solution with respect to changes in parameter values. However, the system is not in state form, but is represented as a set of nonlinear simultaneous equations. For this case the necessary conditions for optimality are difficult to solve. The approach suggested here is to choose a nominal parameter value of economic significance for which the model may be put into state form. Then the existing optimally sensitive control algorithm may be used with some modifications to obtain a near optimal investment strategy for the simultaneous equation system when the parameter deviates from the nominal value. In general, the results indicate an emphasis on education and training expenditures. Sensitivity results indicate that the relative emphasis on long vs short run considerations (i.e. public investment vs consumption) depends on the growth rate parameters in the model.     

Evaluating organizational efficiency resulting from information technology investment: an application of data envelopment analysis

Abstract. Even during this recessionary era, information technology (IT) expenditure in most organizations continues to grow at a high rate. Because of this increased IT expenditure, more and more senior managers are demanding that IT play a greater role in determining their firm's success by helping them increase organizational efficiencies and perhaps even achieve competitive advantage. The existing information systems literature on IT investment and organizational strategic performance, however, provides very little help to senior managers in making before-the-fact IT investment decisions. The present research study puts forth some 'hard' evidence relating IT investment to organizational strategic and economic performance by using data envelopment analysis (DEA). Eight IT investment measures were used as inputs and 10 organizational strategic and economic performance ratios were used as outputs for the DEA model. The results indicate that two-thirds of the organizations in this research study are deemed efficient by DEA. A clear distinction exists between the efficient group and the inefficient group in terms of IT investment and organizational strategic and economic performance. The firms in the efficient group had a much higher return on their information technology investment than the inefficient group. In addition, the DEA results pinpoint the inefficient inputs and deficient outputs for an inefficient firm allowing a senior manager to take corrective actions to compensate for the situation.     

Associating organizational strategic performance with information technology investment: an exploratory research

In the last twenty years, firms have witnessed an explosive growth in information technology (IT) investment. This is true both for manufacturing industries and service industries. The existing literature on IT investment and organizational strategic performance, however, provides very little evidence linking IT investment to organizational strategic and economic performance. The present research investigates whether certain IT investment measures are useful in differentiating organizational economic performance among the most effective information technology users. Eight measures were used to represent IT investment. Ten ratios were utilised to measure organizational strategic and economic performance. The sample organizations were analysed using multidimensional cluster analysis. The results of the analysis suggest that a clear distinction exists between organizations in terms of IT investment and organizational strategic and economic performance. This is true even among the most effective users of information technology. The results also suggest that the majority of the organizations that are investing more in IT seem to be achieving superior strategic and economic performance.     

Economic Policy in a Growth Model with Human Capital,Heterogenous Agents and Unemployment

In this paper we present an endogenous growth model with human capital, heterogenous agents and unemployment. Two types of households are considered. One household acquires human capital or skills through education while the other household remains low-skilled. Sustained growth is the result of human capital accumulation which is a function of the existing human capital employed in the educational sector and of public spending for teaching materials. Both households are affected by unemployment and, if so, receive unemployment benefits. The government levies an income tax and uses its revenues to pay unemployment benefits, to finance transfers to the low-skilled household and to finance human capital accumulation. The paper studies growth and welfare effects of economic policy and presents a stability analysis of the model.      

ICT Capacity as the Investment and Use of ICT: Exploring its Antecedents in Africa

In this paper, we investigate the extent to which economic, human development endowment, political, and population conditions influence information and communication technology (ICT) capacity in African nations using ordinary least squares. We use five variables to measure ICT capacity: ICT expenditure as a percent of GDP (ICTE), ICT expenditure per capita in US dollars (ICTEP), investment in telecoms with private participation (INVTE), Internet users per 100 people (INTUS), and mobile phone subscribers per 1000 people (MOBPS). Unlike ICT adoption and diffusion that focuses on the use of ICT, ICT capacity measures public and private investments in ICT and the use of ICT. The results indicate that ICT capacity of a nation increases with increased (high) corruption index. Further, ICT investment by the private sector depends mainly on human development factors and is not influenced by the perceptions of corruption about a nation. We present theoretical and practical implications of the findings for developing nations in general and African nations in particular.     

Cost model based service placement in federated hybrid clouds

As cloud federation allows companies in need of computational resources to use computational resources hosted by different cloud providers, it reduces the cost of IT infrastructure by lowering capital and operational expenses. This is the result of economies of scale and the possibility for organizations to purchase just as much computing and storage resources as needed whenever needed. However, a clear specification of cost savings requires a detailed specification of the costs incurred. Although there are some efforts to define cost models for clouds, the need for a comprehensive cost model, which covers all cost factors and types of clouds, is undeniable. In this paper, we cover this gap by suggesting a cost model for the most general form of a cloud, namely federated hybrid clouds. This type of cloud is composed of a private cloud and a number of interoperable public clouds. The proposed cost model is applied within a cost minimization algorithm for making service placement decisions in clouds. We demonstrate the workings of our cost model and service placement algorithm within a specific cloud scenario. Our results show that the service placement algorithm with the cost model minimizes the spending for computational services.     

The complexities of electronic services implementation and institutionalisation in the public sector

Electronic service implementation (ESI) in the public sector attempts to improve efficiency, effectiveness, and transparency of governmental departments. Despite having provided the necessary infrastructure and investment, many governments have struggled to realise such aims due to the various forces that challenge implementation and institutionalisation. Using institutional theory as a lens, we explored the forces influencing the implementation and institutionalisation of ESI in the public sector. While our results reinforced previous research in IT implementation and organisational transformation, they showed that the dynamic nature of technology poses unanticipated pressures, and that these can impede the implementation and institutionalisation process.
