Filter Design in the Frequency Domaincesses which are investigated. Since time series are sets of time-ordered observations, we can conceive them as signals or as a sum of such signals. A lot of questions dealing with time series, that is, with signals, can be formalised and transformed into algorithms by using the theory of linear tim

A Re-examination of Long Waves in Aggregate Production Series0 years. However, not only the mere existence of long waves is controversial but also — if their existence is accepted — their precise timing.

Long Waves in Profit Rates in Four Countriesse different concepts and theories as competing ones. Others believe (and I share this opinion) that existing concepts are more complementary than competitive and, furthermore, that we can find common elements among the main approaches.

Rate of Profit and its Determining Factors from a ‘Regulationist’ Point of Viewhe sins under the sun and is the result of the exploitation of labour and the cause of the misery of the people; it is a synonym for parasitism.

The Long Wave as an Endogenous Mechanismocks and influences. Since the roots of this controversy go back to the 1920s, namely to the criticism by Leon Trotsky of Kondratieff’s long-cycle hypothesis, it is perhaps useful to start with a short description of how Kondratieff’s theory related to Marx’s earlier writings, and then present a mor

Long Waves and the Dialectic of Innovations and Conflictsentrepreneur-innovator plays a decisive role in the process. The object of this chapter is to indicate how this logic should be generalised to other kinds of innovations and prompt us to ask basic questions about their origin. This leads us to view innovations as we are defining them in their relati
