Estimating Discount Functions with Consumption Choices over the Lifecycle

Intertemporal preferences are difficult to measure. We estimate time preferences using a structural buffer stock consumption model and the Method of Simulated Moments. The model includes stochastic labor income, liquidity constraints, child and adult dependents, liquid and illiquid assets, revolving credit, retirement, and discount functions that allow short-run and long-run discount rates to differ. Data

The Basic Public Finance of Public-Private Partnerships

Public-private partnerships (PPPs) cannot be justified because they free public funds. When PPPs are desirable because the private sector is more efficient, the contract that optimally trades demand risk, user-fee distortions and the opportunity cost of public funds is characterized by a minimum revenue guarantee and a cap on the firm’s revenues. Yet income guarantees

Sustitución entre Telefonía Fija y Móvil en Chile

En este trabajo se estudia el grado de sustitución entre la telefonía fija y móvil en Chile. Los resultados muestran que la posesión de al menos un teléfono móvil en el hogar reduce el gasto promedio mensual en teléfono fijo en aproximadamente $5400 (31%). A pesar de lo anterior, el cambio estimado en el gasto

Note on Optimal Auctions

This paper considers a general optimal auction problem, with many goods and with a buyer’s utility that can depend non-linearly in his type. We point out that incentive compatibility constraints may be binding even if virtual utilities are strictly increasing in the buyer’s type. More importantly, optimal mechanisms may involve randomizations between different allocations.

Un Análisis Econométrico del Consumo Mundial de Celulosa

En este trabajo se especifica y estima un modelo econométrico para el consumo de celulosa a nivel mundial y desagregado según los principales países consumidores. El modelo utilizado corresponde a uno de demanda derivada para una firma productora de papel representativa que demandará celulosa como un insumo más para su producción. Esta demanda es posteriormente

The Old and the New Reform of Chile’s Power Industry

Chile’s regulatory framework introduced in 1981 remained unchanged for more than 20 years. The reform had a positive effect but several warning signals appeared by the end of the 90s indicating the need to introduce changes. The most important problems were the lack of competition in the generation segment and the reluctance to expand capacity.

Socioeconomic status or noise? Tradeoffs in the generation of school quality information

This paper calculates a time series of simple, standard measures of schools’ relative performance. These are drawn from a 1997-2004 panel of Chilean schools, using individual-level information on test scores and student characteristics for each year. The results suggest there is a stark tradeoff in the extent to which rankings generated using these measures: i)

Mergers and CEO power

In this paper a simple model of mergers in which synergies, private benefits and CEO power play a crucial role is proposed. A merger is modeled as a bargaining process between the acquiring and target board with the gains from a merger divided according to Rubinstein’s alternating-offer game with inside options. Boards consider both firm

Task-Specific Training and Job Design

This paper provides a simple theoretical framework based on a new type of human capital introduced by Gibbons and Waldman (2004), called task-specific training, to understand job design. Mainly, in the presence of task-specific training, promotions might result ex-post in the underutilization of human capital and thus firms at the time of designing jobs should

Performance of an economy with credit constraints, bankruptcy and labor inflexibility

We present a static general equilibrium model of an economy with agents with heterogenous wealth and endogenous credit constraints due to moral hazard. Credit constraints give rise to inefficiencies which are larger if wealth is distributed more unequally. We show that increases in the loan recovery rate improve the efficiency of the economy and raise

Renegotiation without Holdup: Anticipating Spending and Infrastructure Concessions

Infrastructure concessions are frequently renegotiated after investments are sunk, resulting in better contractual terms for the franchise holders. This paper offers a political economy explanation for renegotiations that occur with no apparent holdup. We argue that they are used by political incumbents to anticipate infrastructure spending and thereby increase the probability of winning an upcoming

La dinámica industrial y el financiamiento de las pyme

Las pyme pagan más que las empresas grandes por su financiamiento, se les exigen garantías, se las financia a plazos cortos y muchas no se pueden endeudar. Se piensa que estas prácticas son fallas de mercado que deberían corregirse con intervenciones regulatorias. Sin embargo, nosotros argumentamos que son respuestas apropiadas a (i) el mayor costo
