New algorithms for dating the business cycle


This follows an annual rate of increase of 1. Over the past year, the ICEI has increased by 1. Important Notice The ICEI computed for the most recent month is based, in part, on preliminary labor market data inputs. These data are subject to revision the following month when additional information becomes available. These data input revisions could result in a change in the ICEI when it is finalized. Background The New York State Department of Labor’s Division of Research and Statistics calculates and publishes a monthly composite index of business cycle indicators. More formally known as the Index of Coincident Economic Indicators ICEI , the Index is the equivalent of a weather report for the state’s economy – it is designed to provide reliable and timely information about current economic conditions in New York State. The ICEI does not predict how the state’s economy may be performing in the future; that would be the job of an Index of Leading Economic Indicators, which forecasts economic conditions approximately 12 months into the future. The ICEI model combines and weights four key indicators of statewide economic activity, which have historically moved in conjunction with the state’s business cycles: In turn, all four economic indicators are adjusted for seasonal variation using procedures developed by the U.

Bums-Mitchell procedure, using the business-cycle dating algorithm of Bry and Boschan (). Two recent examples are King and Plosser () and Watson (). The Review of Economics and Statistics, November , 81(4): ? by the President and Fellows of Harvard College and the Massachusetts Institute of Technology.

What are business cycles and how do they affect the economy? May Business cycles are the “ups and downs” in economic activity, defined in terms of periods of expansion or recession. During expansions, the economy, measured by indicators like jobs, production, and sales, is growing–in real terms, after excluding the effects of inflation. Recessions are periods when the economy is shrinking or contracting.

During this period, the average business cycle lasted about five years; the average expansion had a duration of a little over four years, while the average recession lasted just under one year. The chart shows the periods of expansion and recession for the Composite Coincident Indicator Index from to This index, published by The Conference Board http: The chart plots the behavior of the Composite Coincident Indicator Index from to Note that the series typically climbs during expansion periods between the trough and the peak of the business cycle and falls during recessions the shaded areas between the peak and the trough.

How does the NBER determine business cycle turning points? The NBER a private nonprofit nonpartisan research organization, determines the official dates for business cycles. The NBER website http: A recession is a significant decline in activity spread across the economy, that lasts more than a few months and is visible in industrial production, employment, real income, and wholesale-retail sales.

A comparison of two business cycle dating methods

Dictionary , Thesaurus , Medical , Legal , Encyclopedia. Recession A temporary downturn in economic activity, usually indicated by two consecutive quarters of a falling GDP. A recession is a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales.

A recession begins just after the economy reaches a peak of activity and ends as the economy reaches its trough. Between trough and peak, the economy is in an expansion.

Real-Time Measurement of Business Conditions the recent workings of the NBER business cycle dating committee, as described for example by Hall et al. (). On the formal side, latency of business conditions is central to the tedious non-linear filtering algorithm. Ultimately, however, the similarities between our work and others.

Wednesday, January 12, eHarmony: Integrating Intelligence with Online Dating Background Many internet dating sites have sprung up over the past fifteen years… such as eHarmony , Match. While the most of these sites seek to aggregate profiles for users, eHarmony and Chemistry have created a different product model by integrating psychological profiling, proprietary algorithm development, and selective filtering to enhance the customer experience.

Business cycle dating algorithm The business cycle features approach to model comparison requires a measure of the business cycle for both actual and simulated data. In the business cycle features literature, the business cycle is defined as.

May Abstract In this paper we compare alternative approaches for dating the Euro area business cycle and analyzing its characteristics. First, we extend a commonly used dating procedure to allow for length, size and amplitude restrictions, and to compute the probability of a phase change. Second, we apply the modified algorithm for dating both the classical Euro area cycle and the deviation cycle, where the latter is obtained by a variety of methods, including a modified HP filter that reproduces the features of the BK filter but avoids end-point problems, and a production function based approach.

Third, we repeat the dating exercise for the main Euro area countries, evaluate the degree of syncronization, and compare the results with the UK and the US. Fourth, we construct indices of business cycle diffusion, and assess how spread are cyclical movements throughout the economy. Finally, we repeat the dating exercise using monthly industrial production data, to evaluate whether the higher sampling frequency can compensate the higher variability of the series and produce a more accurate dating.

History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.

Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.

The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery. Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations. They did not have the benefit of cheap, off the shelf, mass produced batteries.

For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item.

The Econbrowser Recession Indicator Index

Or worse yet, that Oregon falls first and recovers last? Something along these lines really does seem to be the conventional wisdom. In this case, the conventional wisdom is wrong. Today I want to focus just on employment, one of the only really good indicators available at the local level. First, a quick look at employment growth in recent decades.

A new strategy for dating the business cycle turning points, both in the classical and the deviation sense, is presented. After reviewing the available solutions, and in particular the popular Bry and Boschan routine, the role of filtering operations in the preliminary identification of candidate.

Department of Transportation, Bureau of Transportation Statistics, http: American Trucking Association, http: Freight activity is typically measured by tons, value, and ton-miles of cargo moved. Not all metrics are available monthly for all modes. Trucking figure 2 Data on movements by truck are provided through a truck tonnage index, calculated by the American Trucking Associations ATA ; this index is a relative measure of the total tonnage transported by the motor carrier industry for a given month.

For the most recent data, BTS uses the preliminary value of the truck tonnage index provided by ATA ; when the official data become available, the preliminary values are replaced. Air figure 3 U. As with the air revenue passenger-miles, 6 the ton-mile data are drawn from air carrier reports to BTS on Form 41 Schedule T , which contains extensive information on air freight movement as well as passenger travel by air.

Rail figures 4 and 5 The monthly rail freight data from to the present are tabulated from weekly carloads and intermodal units made available by the Association of American Railroads AAR. These quarterly values are then expanded, using linear interpolation, to monthly values. Department of Transportation, Federal Railroad Administration, http:

Additional Information In lieu of an abstract, here is a brief excerpt of the content: In this chapter we provide an overview of business cycle dynamics around recessions in EMEs. We first analyze the main properties of recessions in EMEs during the period — This chapter begins with a brief summary of the data set and methodology we use for this part of the analysis. We then present the basic stylized features of recession episodes, including duration and amplitude.

ESTIMATING TURNING POINTS USING LARGE DATA SETS James H. Stock Mark W. Watson There is a fairly large literature on business cycle dating using modern time series methods, recently surveyed by Hamilton (). algorithm.2 Dating Using a Simple Random Sample of Disaggregated Series We imagine a population of economic time series.

First, the announcements often come long after the event. Second, outsiders might wonder perhaps without justification whether the dates of announcements are entirely independent of political considerations. For example, there might be some benefit to the presidential incumbent of delaying a declaration that a recession had started or accelerating a declaration that a recession had ended. For these reasons, it is worth exploring whether one could perform a similar function using purely objective summaries of the data.

Any such effort faces a tradeoff between two objectives. On the one hand, we might hope to use as much information in as much detail as possible. On the other hand, the more simple and parsimonious the approach, the more likely it is to prove to be robust as the economy changes and data get revised.

Since this code was limited to four digits, TJD recycled to zero on MJD , or October 10, , “which gives a long ambiguity period of Only whole days are represented. Time of day is expressed by a count of seconds of a day, plus optional milliseconds, microseconds and nanoseconds in separate fields. Later PB-5J was introduced which increased the TJD field to 16 bits, allowing values up to , which will occur in the year

A business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. Economists note, however, that complete business cycles vary in length. The duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. Some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations.

But the term “business cycle” is still primarily associated with larger industry-wide, regional, national, or even international business trends. This is the most unwelcome stage of the business cycle for business owners and consumers alike. A particularly severe recession is known as a depression. Recovery Also known as an upturn, the recovery stage of the business cycle is the point at which the economy “troughs” out and starts working its way up to better financial footing.
