Housing market dynamics and welfare

We augment a closed-economy DSGE model with collateral constraints tied to real estate values by incorporating the time-to-build phenomenon in the housing construction sector. Adding construction sector delays significantly improves business cycle properties of the model relative to the versions with no time-to-build delays or with permanently fixed housing stock. We also find that in the presence of construction lags adding housing prices to the central bank policy function increases aggregate welfare in the economy by up to 0.3 percent of consumption. This result is robust to several specifications of the Taylor rule and to changes in key parameter values.Housing prices; housing construction; time-to-build; welfare.

Thinking Beyond Credit

Credit is often seen as an indispensable vehicle for the poor to get out of poverty, or as the tool that allows farmers to get access to new technologies, to increase productivity and their incomes. But many existing credit programmes often undermine farmers’ independence, tie them into dependency relationships, and oblige them to take all the risk. There are better ways to help farmers build their own resource base and independenc

Ending open defecation in rural Tanzania: which factors facilitate latrine adoption?

Diarrheal diseases account for 7% of deaths in children under five years of age in Tanzania. Improving sanitation is an essential step towards reducing these deaths. This secondary analysis examined rural Tanzanian households sanitation behaviors and attitudes in order to identify barriers and drivers to latrine adoption. The analysis was conducted using results from a cross-sectional study of 1000 households in five rural districts of Tanzania. Motivating factors, perceptions, and constraints surrounding open defecation and latrine adoption were assessed using behavioral change theory. Results showed a significant association between use of improved sanitation and satisfaction with current sanitation facility (OR: 5.91; CI: 2.95-11.85; p = 0.008). Livestock-keeping was strongly associated with practicing open defecation (OR: 0.22; CI 0.063-0.75; p < 0.001). Of the 93 total households that practiced open defecation, 79 (85%) were dissatisfied with the practice, 62 (67%) had plans to build a latrine and 17 (18%) had started saving for a latrine. Among households that planned to build a latrine, health was the primary reason stated (60%). The inability to pay for upgrading sanitation infrastructure was commonly reported among the households. Future efforts should consider methods to reduce costs and ease payments for households to upgrade sanitation infrastructure. Messages to increase demand for latrine adoption in rural Tanzania should integrate themes of privacy, safety, prestige and health. Findings indicate a need for lower cost sanitation options and financing strategies to increase household ability to adopt sanitation facilities

Banks as blockholders

In this paper, we analyze the effects of banks as main blockholders on a firm's returns and on the concentration of ownership in the hands of the controlling blockholders. Compared with previous studies, we approach to this problem by taking into consideration the type of blockholders building up coalitions with banks for controlling a firm. This allows us to reconcile different results, reported in relevant literature, on the impact of banks' ownership of a firm on its returns. In short, we argue that the effect is only negative when banks are the main blockholders or when they build up coalitions with other banks. We prove empirically our theoretical contentions making use of a sample of Spanish firms for the period 1996-2000

IEEE Standard 1500 Compliance Verification for Embedded Cores

Core-based design and reuse are the two key elements for an efficient system-on-chip (SoC) development. Unfortunately, they also introduce new challenges in SoC testing, such as core test reuse and the need of a common test infrastructure working with cores originating from different vendors. The IEEE 1500 Standard for Embedded Core Testing addresses these issues by proposing a flexible hardware test wrapper architecture for embedded cores, together with a core test language (CTL) used to describe the implemented wrapper functionalities. Several intellectual property providers have already announced IEEE Standard 1500 compliance in both existing and future design blocks. In this paper, we address the problem of guaranteeing the compliance of a wrapper architecture and its CTL description to the IEEE Standard 1500. This step is mandatory to fully trust the wrapper functionalities in applying the test sequences to the core. We present a systematic methodology to build a verification framework for IEEE Standard 1500 compliant cores, allowing core providers and/or integrators to verify the compliance of their products (sold or purchased) to the standar

Optimal Litigation Strategies with Signaling and Screening

This paper examines the strategic effects of case preparation in litigation. Specifically, it shows how the pretrial efforts incurred by one party may alter its adversary’s incentives to settle. We build a sequential game with one-sided asymmetric information where the informed party first decides to invest, or not, in case preparation, and the uninformed party then makes a settlement offer. Overinvestment, or bluff, always prevails in equilibrium: with positive probability, plaintiffs with weak cases take a chance on investing, and regret it in case of trial. Furthermore, due to the endogenous investment decision, the probability of trial may (locally) decrease with case strength. Overinvestment generates inefficient preparation costs, but may trigger more settlements, thereby reducing trial costs.case preparation, settlement, trial, signaling

Limit Orders, Trading Activity, and Transactions Costs in Equity Futures in an Electronic Trading Environment

The behaviour of limit order quotes and trading activity are studied using a unique and rich database that includes the identity of market participants from a fully automated derivatives market. The analysis is performed using transactions records for three aggregated trader types and three trade identifiers, with trades stamped in milliseconds for the SXF, the equity futures contract of the Montreal Exchange. The identifiers distinguish trades between principals; agency based trades, as well as transactions that are conducted for risk management as opposed to speculative purposes. Agency related trades are shown to represent the largest amount of trading activity relative to other account types. Over 90% of trades in this electronic market are limit orders. The limit order book, especially the depth 1 order, has a dominant role in providing liquidity and in explaining market participants’ trading behaviour. Participants in the SXF reference their trades to the best limit order depth. Hence, investors with large positions or investors who want to build a large position have to strategically split large orders to close/build their position, according to the depth of the best limit order, to ameliorate price impact and information leakage effects. In addition, the results show that traditionally measured spreads have no relationship with trading costs.Limit Orders, Trading Activity, Transactions Costs, Electronic Trading

Winners and Losers in Housing Markets

This paper is a quantitatively-oriented theoretical study into the interaction between housing prices, aggregate production, and household behaviour over a lifetime. We develop a life-cycle model of a production economy in which land and capital are used to build residential and commercial structures. We find that, in an economy where the share of land in the value of structures is large, housing prices react more to an exogenous change in expected productivity or the world interest rate, causing large redistribution effects between net buyers and net sellers of houses. Changing the financing constraint, however, has limited effects on housing prices.Real estates, Land, Housing Prices, Life cycle, Collateral constraints.

Privatization of Knowledge: Did the U.S. Get It Right?

Brilliant ideas are key to economic growth. They often emerge from scientific discoveries with no immediate commercial value - so rewards may not be aligned to effort. Should basic research be publicly or privately funded? And, to foster innovation and growth, what kinds of discovery should be protected? Post 1980, the US intellectual property institutions facilitated the patentability of basic research. The European and other patenting regimes are slowly changing in the same direction, also encouraged by TRIPs. Did the US choose the better path? We build a Schumpeterian model to re-assess this important turning point.R&D and Growth, Sequential Innovation, Research Tools, Patent Laws, Kremer Mechanism
