Theoretical literature on monetary and fiscal policy have suggested that shadow economy or the informal sector is a powerful buffer which absorbs large proportions of the transmission channels of macroeconomic policies. We develop a theoretical DSGE model with shadow economy and investigate their impact on the transmissions of monetary and fiscal policies in developing and emerging countries. The thesis is organised in three chapters as follows. Chapter one seeks to examine the transmission effects and efficacy of monetary policy and other structural shocks with the interaction of shadow economy. Our model determines whether the presence of shadow economy affects the responses of the official economy and also clarifies the changes in the transmission mechanism within both sectors. The second chapter describes a new Keynesian DSGE model with shadow economy and investigate the role of fiscal policies over the aggregate business cycle. In this chapter, we sought to elucidate whether the presence of shadow economy dampens or amplifies the effect of fiscal policy transmissions. We further tried to understand whether fiscal policies can be used to stabilise the economy in response to shocks. In chapter three, we study the interplay of rule-of-thumb consumers and the presence of shadow economy focusing on fiscal policy disturbances. Our basic motivation is to know whether the incorporation of shadow economy weakens the amplifying effect of rule-of-thumb consumers on fiscal multipliers.
Gli studi sulla politica monetaria e fiscale suggeriscono che l'economia sommersa o informale è un potente cuscinetto in grado di assorbire i canali di trasmissione delle politiche macroeconomiche. In questo lavoro, sviluppiamo un modello DSGE con economia sommersa al fine di analizzarne l’impatto sui canali di trasmissione delle politiche monetarie e fiscali nei paesi emergenti e in via di sviluppo. La tesi è organizzata in tre capitoli. Il primo capitolo cerca di esaminare gli effetti di trasmissione e l'efficacia della politica monetaria e di altri shock strutturali attraverso l’interazione con l’economia sommersa. Il nostro modello determina se la presenza di un'economia sommersa influisce sulle risposte dell'economia ufficiale e chiarisce anche i cambiamenti nel meccanismo di trasmissione all'interno di entrambi i settori. Il secondo capitolo descrive un nuovo modello DSGE keynesiano con economia sommersa e analizza il ruolo delle politiche fiscali sul ciclo economico aggregato. In questo capitolo, abbiamo cercato di chiarire se la presenza di un'economia sommersa riduca o incrementi l'effetto delle trasmissioni di politica fiscale. Abbiamo anche cercato di capire se le politiche fiscali possono essere utilizzate per stabilizzare l'economia in risposta agli shock. Nel terzo capitolo, studiamo l'interazione tra i consumatori e la presenza di un'economia sommersa focalizzandoci sugli shock della politica fiscale. L‘obiettivo è sapere se l'introduzione di un'economia sommersa indebolisca l'effetto amplificativo dei consumatori sul moltiplicatore fiscale.

Abstract
Theoretical literature on monetary and fiscal policy have suggested that shadow economy or the informal sector is a powerful buffer which absorbs large proportions of the transmission channels of macroeconomic policies. We develop a theoretical DSGE model with shadow economy and investigate their impact on the transmissions of monetary and fiscal policies in developing and emerging countries. The thesis is organised in three chapters as follows. Chapter one seeks to examine the transmission effects and efficacy of monetary policy and other structural shocks with the interaction of shadow economy. Our model determines whether the presence of shadow economy affects the responses of the official economy and also clarifies the changes in the transmission mechanism within both sectors. The second chapter describes a new Keynesian DSGE model with shadow economy and investigate the role of fiscal policies over the aggregate business cycle. In this chapter, we sought to elucidate whether the presence of shadow economy dampens or amplifies the effect of fiscal policy transmissions. We further tried to understand whether fiscal policies can be used to stabilise the economy in response to shocks. In chapter three, we study the interplay of rule-of-thumb consumers and the presence of shadow economy focusing on fiscal policy disturbances. Our basic motivation is to know whether the incorporation of shadow economy weakens the amplifying effect of rule-of-thumb consumers on fiscal multipliers.File | Dimensione | Formato | |
