Business model schema: business model innovation tool based on direct causal mechanisms of profit

ABSTRACT

Defining business model as the logic/mode/way/framework to seek profit/money and glancing at the evolution of concept business, this paper develops a business model schema (BMS) as a holistic two-dimensions multi-level tool/method for business model innovation (BMI) based on the direct causal mechanisms of profit (DCMP). First, this paper takes DCMP as the logical/theoretical framework by which business model innovation process is identified and specified. And according to that process, it develops a BMS, illustrates an example of BMS to show up its practical usefulness, compares the similarities and differences between BMS and the existing powerful one business model canvas (BMC), and finally asserts that BMS must be a good and useful method in theory and practice because it stands on DCMP that ensures the genuine causality of profit and also it turns out practically useful, recalling the Kurt Lewin’s maxim (1945), “There is nothing so practical as a good theory.     

EFFECTS OF PUBLIC TRANSIT ON AUTOMOBILE OWNERSHIP AND USE IN HOUSEHOLDS OF THE USA

This study develops econometric models to predict the effect of access to and distance to public transit on automobile ownership and miles driven. Ordered logit model is used for automobile ownership and multiple regression model is used for vehicle miles traveled (VMT).
Inverse square root of transit distance is used as a measure for transit accessibility. Important findings in the analysis are (i) the number of licensed drivers is the primary determinant of the number of automobiles owned, (ii) the presence of children is not a significant factor in automobile ownership and VMT, and (iii) the VMT of multi-vehicle households is more sensitive to transit than one-vehicle households. Transit simulations are performed by improving the distance to and access to public transit. The results showed that total VMT in National Ambient Air Quality Standard non-attained metropolitan statistical area is reduced by 11% (approximately 60 billion miles) with 0.1 miles simulation.     

The participation of Russian households in the informal economy: Evidence from the VTsIOM data

This study presents the size and structure of secondary employment in Russia, analyses the determinants of Russian informal secondary employment, and discusses differences between job qualifications in a main job and those in a secondary job. We estimate that 27 percent of Russia’s GDP was produced in the informal economy during 1997–98 and informal secondary employment amounts to about 20 percent of value added produced in the informal economy. We found that the probability of holding an informal secondary job as opposed to a formal one is positively associated with higher wage rates and lower education. However, there is little evidence that low income is correlated with holding an informal secondary job. We also found evidence that an informal secondary job requires lower job qualifications as compared to a formal one. Again, low income is not significant in determining differences between job qualifications in a main job and those in a secondary job. JEL classification: J22, J24, O17, P20.

Alternative transportation modes in an urban land use model: A general equilibrium approach

This paper presents and analyzes a general equilibrium transportation demand model. The model was applied to hypothetical cities with populations of 1 and 2 million. Data and coefficients for those cities were obtained from existing metropolitan areas of equivalent sizes. A subway system is found to be uneconomical in the hypothetical city with one million population and with an average population density of 4400 per square mile. However, it is found to be economical and desirable for the hypothetical city with two million population and with an average density of 6900 per square mile.     

Stochastic reserve changes and expansion of bank credit: The case of additional risks

In this paper we examine the effects of introducing additional risks to the Orr-Mellon-Cooper model on the asymptotic behavior of bank credit expansion, and derive monetary policy implications therefrom. Our model of additional risks corrects a loss of generality existing in the Orr-Mellon-Cooper model. It shows that the local solution for optimal credit expansion is the global solution, regardless of the parameters of the reserve loss functions, when the default risk is introduced. The analysis further points out necessary conditions to determine the direction of credit changes caused by a monetary injection under uncertainty.     

An alternative model for fair share allocation of lower income housing

A linear programming model was developed and presented for fair-share allocation of lower income housing as an alternative to existing heuristic models. The model is applied for the Middlesex County region in pursuit of a regional fair-share of lower income housing needs for the year 1975 for each township in the county. The results are presented and compared with those of the Court's allocation, held by the Superior Court of New Jersey in May 1976 for the Middlesex County region.
