The fixed-route traveling salesman problem with appointments, simply the appointment problem, is concerned with the following situation. Starting from home, a traveller makes a scheduled visit to a set of sponsors and returns home. If a sponsor in the route cancels her appointment, the traveller...

We study the problem of allocating heterogeneous indivisible tasks in a multi-object-demand model (i.e., each agent can be assigned multiple objects) where monetary transfers are allowed. Agents. costs for performing tasks are their private information and depend on what other tasks they are...

We investigate the implications of welfare lower bounds together with queue-efficiency and strategyproofness in the context of the queueing problem. As a consequence, we provide alternative characterizations of the k-pivotal mechanisms (Mitra and Mutuswami [13]). First, we introduce the...

In Shapiro and Pincus (2008), we proposed a method for arriving at just compensation of private owners of urban land, in cases like Kelo v New London, in which government has plans to use eminent domain to `take' private properties, to be assembled into a single parcel for some public purpose....

Trade theorists and policymakers have until recently ignored trade costs, but as tariffs have fallen it is apparent that trade costs are a significant obstacle to trade and they are not simply determined by geography or commodity characteristics. We analyse country-by-country variations in trade...

The standard one-sector real business cycle model is unable to generate expectations-driven business cycles. The current paper shows that this conundrum can be solved by adding countercyclical markups and modest capital adjustment costs.

This paper concerns the impact of global crises in 2007-9 on Asian economies.

To what extent has Sub-Saharan Africa's slow economic growth over the past five decades been due to price and trade policies that have discouraged production of agricultural relative to non-agricultural tradables? This paper uses a new set of estimates of policy distortions to relative prices to...

We estimate the income elasticity of government expenditures using variation in the international oil price as a plausibly exogenous source of within-country variation of countries' permanent income. Our short run elasticity estimates, between 0.25-0.50, are generally somewhat smaller than the...

In 2010-11 over $45 billion GST monies, and about $24b of other grants, will be distributed between the States and Territories on the recommendation of the Commonwealth Grants Commission. The Commission is instructed to implement Horizontal Fiscal Equalisation (HFE); and not to be concerned with...
