What’s on the exam? ECO305

In ECO305 Mgr Econ on February 22, 2009 at 13:09

Remember the exam is on Wednesday.  You will be asked to respond to chapters 3,4,5,6,7,8.  the questions will be mostly problems of the type students did in class, stressing these concepts.

Consumer Theory indifference maps, marginal rate of substitution, budget line, optimality condition (where the consumer makes the optimal choice), substitution and income effect when prices change

Supply and Demand

Estimating Supply and Demand – Q=f(P,other prices, Income, other factors)

Elasticity – Price elasticity of demand, income elasticity of demand, cross elasticity.  Elasticity and maximum revenue.

Production functions – isoquants, optimality conditions, calculating with production functions. Re3turns to scale and to a factor.  Costs, cost minimization using isoquants and the budget line. Short run and long run cost curves, average cost, average variable cost, marginal cost, relations.  the supply curve is the marginal cost line above the TVC line.  Factor demand curves.  Long run and short run costs.

Market strructure – Perfect competition, Monopoly. How do we find the firm’s optimal quantity and price under these circumstances?  what happens when there is a profit under perfect competition?  Oligopoly. strategic analysis with Nash equilibrium. cournot duopoly calculation.  strategic games and cartels, prisoner’s dilemma, and finding solutions to strategic games by the method of iterated dominance.

Pricing with market power – single pricing (monopoly case).  Higher profits througn two part tariff. Price discrimination.  Segmented pricing as in Snowfish.  Menu pricing, coupons, rebates.

Value Creation and Capture – Transaction costs (reducing them- the effect). Noncooperative pricing of complements, and coordination.  Superior factors of production. Why does producer surplus captured by superior assets flow to the assets themselves in the long run?

Hope it helps.

ABS SafeNet software and modules

In MGT 335 Advanced Computing on February 6, 2009 at 12:19

ABS SafeNet Introduction

Safe Net is a limited suite of products for certain specific ship needs.  It forms part of a broader suite of products handling many aspects of ship management and fleet management, which is available from their subsidiary ABS Nautical Systems (NS).

Fleet Management Solutions ABS Nautical Systems

All are built on the MySQL open source database.  SafeNet itself seems to run on a browser, whereas the Nautical Systems (NS) modules (which cost extra) are run on windows. rather than a browser.  That means in the NS modules the client PC systems probably do a lot of the business logic, rather than isolating the business logic from the user interface (the web browser). 

The whole suite would comprise part of an Enterprise Resource Planning (ERP) system, specially adapted and extended for ship and fleet needs.  There is much attention to international standards record keeping, and to the survey cycle and maintenance cycles.  Portions are Inventory and Purchasing, Maintenance and Repair, Quality and Compliance, Crew management, Payroll, Voyage Mgt, Hull Maintenance.

While Safe Net itself is of great interest and utility to a ship operator, the entire suite is of interest to a shipping company or owner as well, and could be well used by both ship staff and corporate.

NS state that the system can be interfaced to a corporate ERP system.  This probably takes custom programming, which they want to sell customers.  They give some examples of interfaces they have built for customers.

It is a natural to include in our courses because MySQL is the DB system we teach in our MGT335 course.
